1) Solve for x.
(3.x - 2)°
(14x -19°
(9x+7)
Answer:
x = 12
Step-by-step explanation:
We will label the unknown interior angle of the triangle d.
14x - 19 + d = 180
14x + d = 199
d = 199 - 14x
199 - 14x + 3x + 9x + 7 - 2 = 180
199 - 2x +5 = 180
204 - 2x = 180
204 = 180 + 2x
2x = 24
x = 12

Savannah needs to order some new supplies for the restaurant where she works. The
restaurant needs at least 694 knives. There are currently 262 knives. If each set on
sale contains 12 knives, which inequality can be used to determine s, the minimum
number of sets of knives Savannah should buy?
Answer:
\(s\geq 36\)
Step-by-step explanation:
Step 1, how many knives to buy?
The restaurant already has 262 knives. We can subtract this number from their needed 694 knives to find how many they still need:
\(694-262=432\) knives.
Step 2, how many sets of knives?
The restaurant needs to buy 432 knives. We know the knives come in sets of 12, so we can divide to find the # of packs she needs to buy, determined by variable s.
Notice how the restaurant needs to buy a minimum of 694 knives, hence we use a greater or equal than symbol:
\(\fbox{\frac{432}{12} \geq s}\\\)\(s\geq \frac{432}{12}\)
\(s\geq 36\)
I hope this helps! Let me know if you have any questions :)
The inequality that can be used to determine s, the minimum number of sets of knives Savannah should buy is 694 ≥ 262 + 12s.
Given that;
The restaurant needs at least 694 knives. There are currently 262 knives.
Here, each set on sale contains 12 knives.
Let us assume that;
The minimum number of sets of knives Savannah should buy = s
Hence the inequality for the given condition is,

There are 210 girls in the 7th grade. For every five girls, thereare three boys. Which three (3) proportions can be used to find the numberof boys?The proportions are:1. 5/3 = 210/x2. x/210 = 3/53. x/5 = 3/2104.5/210 = 3/x5. 210/3 = x/5
We know that the ratio for girls and boys is 5:3, this means that there are five girls for three boys. We also know that there are 210 girls but we don't know how many boys there are, nevertheless the ratio should be the same, this means that the proportion we are looking for is:
\(\frac{5}{3}=\frac{210}{x}\)Then, the first proportion is 1.
If we switch the denominator and numerator in each of the sides of the last equality we get an equivalent one, then:
\(\frac{3}{5}=\frac{x}{210}\)Then, the second option is 2.
Finally if we pass the five to the right and the x to the left in the last equation we get:
\(\frac{3}{x}=\frac{5}{210}\)Then, the thir option is 4.

Which car should Andre buy? How many more miles per gallon can he
drive in this car than the other car?
Answer: Andre should buy Car 2. Brainliest?
Step-by-step explanation:
To compare the gas mileage of the two cars, we need to find out how many miles each car can travel per gallon of gas.
For Car 1: y = 25x
This means that for every gallon of gas used (x), the car can travel 25 times that amount in miles (y). So, the gas mileage for Car 1 is 25 miles per gallon (mpg).
For Car 2: we can calculate the miles per gallon by dividing the total miles traveled by the number of gallons of gas used:
For 2 gallons of gas, the car can travel 60 miles. So, the gas mileage is 30 mpg (60 miles ÷ 2 gallons).
For 5 gallons of gas, the car can travel 150 miles. So, the gas mileage is 30 mpg (150 miles ÷ 5 gallons).
For 7 gallons of gas, the car can travel 210 miles. So, the gas mileage is 30 mpg (210 miles ÷ 7 gallons).
For 8 gallons of gas, the car can travel 240 miles. So, the gas mileage is 30 mpg (240 miles ÷ 8 gallons).
For 11 gallons of gas, the car can travel 330 miles. So, the gas mileage is 30 mpg (330 miles ÷ 11 gallons).
Therefore, Car 2 has a consistent gas mileage of 30 mpg.
From the above calculations, we can see that Car 2 has a better gas mileage compared to Car 1. Car 2 can travel 30 miles on a gallon of gas, while Car 1 can only travel 25 miles on a gallon of gas.
Therefore, Andre should buy Car 2 if he wants to get the best gas mileage. Car 2 can travel 5 more miles per gallon than Car 1.
Penelope made note of all the bicycles and cars she could see parked or locked on a certain city block. All the cars had exactly four wheels, and all the bicycles had exactly two wheels. How many wheels were on the block if there were 7 bicycles and 15 cars? How many wheels were on the block if there were x bicycles and y cars? Total wheels, 7 bicycles and 15 cars: Total wheels, x bicycles and y cars:
Answer:
1 Block = 75 Wheels, and
1 Block = 2x + 4y
Step-by-step explanation:
Let C and B stand for Cars and Bicycles. W is for wheels.
We know that:
1C = 4W, and
1B = 2W
How many wheels were on the block if there were 7 bicycles and 15 cars?
1 Block = 7B + 15C
1 Block = 7(2W) + 15(4W)
1 Block = 14W + 60W
1 Block = 75 Wheels
How many wheels were on the block if there were x bicycles and y cars?
1 Block = 2x + 4y

The question is asking for pairs of congruent triangles but lacks key information needed to accurately answer this, such as lengths or angles. Congruent triangles are identified in geometry based on either side-lengths or angles.
Explanation:The question is about congruent triangles, which in mathematics means triangles that have the same size and shape. But to accurately answer which pairs show two congruent triangles, we need more information. The options provided include 'A', 'B', and 'C' but without knowing more about these elements (for example their lengths or angles), it is impossible to determine which are congruent. Congruent triangles are identified in geometry based on either side lengths (SSS: Side-Side-Side, SAS: Side-Angle-Side, ASA: Angle-Side-Angle) or angles (AAS: Angle-Angle-Side, HL: Hypotenuse-Leg for right triangles). Without this vital information, we cannot definitively answer the question. Be sure to verify all the properties required to prove two triangles congruent.

g(x) has the greatest maximum value.
All three functions share the same range.
Oh(x) has a range of all negative numbers.
All three functions share the same domain.
Answer:
The statements that can be used to compare the characteristics of the functions are:
1. g(x) has the greatest maximum value.
2. All three functions share the same domain.
Explanation:
- The table shows the values of three functions - f(x), g(x), and h(x) - evaluated at different values of x.
- We cannot determine the domain of f(x) or h(x) from the given table but we can see that g(x) has a domain of all real numbers.
- We can see that g(x) has the highest maximum value among the three functions, which is 8.
- We cannot determine the range of f(x) or g(x) from the given table but we can see that h(x) has a range of all negative numbers.
- We cannot say anything about the domain or range of f(x) based on the given table.
- Therefore, the two statements that can be used to compare the characteristics of the functions are: g(x) has the greatest maximum value and all three functions share the same domain.

Phil has $20,000, part of which he invests at 8% interest and the rest at 6%. If the total income from the two investments was $1460, how much did he invest at 6%?
Answer: 7000
Step-by-step explanation:
Let the amount invested in 8% account be P1 and the amount invested in 6% account be P2
. If the total amount invested is $20,000 then:
P1+P2=20,000. (Eq. 1)
The interest earned in one year from the 8% account is:
I1=0.08P1
and the interest earned in one year from the 6% account is:
I2=0.06P2
If the total interest earned is $1460, then:
I1+I2=1460
0.08P1+0.06P2=1460
(Eq. 2) From Eq. 1 :
P1=20000−P2
Substituting this into Eq. 2:
0.08 (20000−P2) + 0.06P2 = 1460
1600 − 0.08P2 + 0.06P2 = 1460
0.02P2 = 140
P2 = 140 / 0.02
P2 = 7000
Hence, he invested $7000 at the rate of 6%.
Brooklyn is going to invest in an account paying an interest rate of 3.5% compounded continuously. How much would Brooklyn need to invest, to the nearest ten dollars, for the value of the account to reach $64o in 9 years?
Brooklyn needs to invest $432.43, rounded to the nearest ten dollars.
To determine how much Brooklyn needs to invest in an account that pays a continuously compounded interest rate, we can use the formula:
A = \(Pe^(^r^t^)\)
where A is the future value of the account, P is the principal investment, e is the mathematical constant approximately equal to 2.71828, r is the interest rate, and t is the time in years.
In this case, we want the future value of the account to be $640, the interest rate is 3.5% (or 0.035 as a decimal), and the time is 9 years. We can substitute these values into the formula and solve for P:
640 = \(Pe^(^0^.^0^3^5^*^9^)\)
640 = Pe^0.315
P =\(640/e^0^.^3^1^5\)
P = 432.43
Therefore, to have a future value of $640 in 9 years with a continuously compounded interest rate of 3.5%.

F5
The simplified boolean expression for F5 is F5 = P OR (NOT R). In this expression, P represents one boolean variable, and (NOT R) represents the negation of another boolean variable R. The OR operator combines the two variables, resulting in the final boolean expression F5.
To simplify the boolean expression F5 = (P AND Q) OR (R AND NOT P), we can apply Boolean algebra rules to reduce it to its simplest form.
Step 1: Apply De Morgan's laws
NOT (R AND NOT P) can be simplified as (NOT R) OR P.
Step 2: Distributive property
F5 = (P AND Q) OR ((NOT R) OR P)
Step 3: Apply associative property
F5 = (P AND Q) OR (P OR (NOT R))
Step 4: Apply absorption law
F5 = P OR (P OR (NOT R))
Step 5: Apply idempotent law
F5 = P OR (NOT R)
By simplifying the expression, we have reduced it to its simplest form while preserving its logical meaning. The simplified expression can be used to analyze and evaluate logical circuits or systems where the variables P and R are used.
Remember, boolean algebra allows us to manipulate and simplify complex logical expressions by applying various rules and properties. These simplifications help in understanding and analyzing logical operations in digital systems and circuits.
