================================================

Explanation:

In math, the term "substitution" basically means "replace". Keep in mind that x is a placeholder for a number. Think of it as a box we place a number inside.

We have the items {6, 16, 24} to use as replacements for x. We only do one number at a time

Let's try x = 6

4 + x < 20

4 + 6 < 20 ... replace x with 6

10 < 20 ... this is a true statement as 10 is less than 20

So x = 6 is a solution

Let's try x = 16

4+x < 20

4+16 < 20

20 < 20 ... this is false because we can't have a number smaller than itself

Lastly, let's try x = 24

4+x < 20

4+24 < 20

28 < 20 ... also false; 28 is not smaller than 20

We've shown that x = 16 and x = 24 are not solutions. Only x = 6 is a solution from the set {6,16,24}. This is why the answer is choice B.

-----------------

Alternative method:

4+x is the same as x+4. We can add two numbers in any order we want.

x+4 < 20 solves to x < 16 after subtracting 4 from both sides. So the set of solutions is anything smaller than 16. Looking at {6,16,24} we see that the only allowed answer is x = 6.

x = 16 is not a solution because x < 16 would turn into 16 < 16, but again we can't have a number smaller than itself.

Answer:

192 hours per day / 8 hours per person per day = 24 people

Step-by-step explanation:

Assuming each person works for 8 hours a day, the total number of hours needed to complete the project is:

720 person-days x 8 hours = 5,760 hours

To complete the project in 30 days, the total number of hours needed per day is:

5,760 hours / 30 days = 192 hours per day

Answer:

47.53 miles

Step-by-step explanation:

6.79×7= 47.53

Answer:

47.53 miles total for the week.

Step-by-step explanation:

so if she ran 6.79 for each 7 days that would be:

6.79 * 7 = 47.53

or

6.79 + 6.79 + 6.79 + 6.79 + 6.79 + 6.79 + 6.79 =  47.53

\(\textsf{(d)} \quad 3x^2-24x+48\)

\(\textsf{(e)} \quad 9x^2-72x+144\)

(f)    Not equivalent.

Step-by-step explanation:

Equivalent expressions are expressions that simplify to the same expression.  

Part (a)

\(\begin{aligned}&\textsf{Add 3 to $x$}: & \quad x+3\\&\textsf{Subtract the result from $1$}: & \quad 1-(x+3)\\&\textsf{Double}: & \quad 2[1-(x+3)]\\&\textsf{Expand}: & \quad 2[1-x-3]\\&\textsf{Simplify}:&2[-x-2]\\&& -2x-4\end{aligned}\)

Part (b)

\(\begin{aligned}&\textsf{Add 3 to $x$}: & \quad x+3\\&\textsf{Double}: & \quad 2(x+3)\\&\textsf{Subtract $1$ from the result}: & \quad 2(x+3)-1\\&\textsf{Expand}: & 2x+6-1\\&\textsf{Simplify}:&2x+5\end{aligned}\)

Part (c)

The expressions are not equivalent.  

The coefficients of the x-variables are the negatives of one another, and the constants are different numbers.

Part (d)

\(\begin{aligned}&\textsf{Subtract 4 from $x$}: & \quad x-4\\&\textsf{Square the result}: & \quad (x-4)^2\\&\textsf{Triple}: & \quad 3(x-4)^2\\&\textsf{Expand}: & \quad 3(x^2-8x+16)\\&\textsf{Simplify}:& 3x^2-24x+48\end{aligned}\)

Part (e)

\(\begin{aligned}&\textsf{Subtract 4 from $x$}: & \quad x-4\\&\textsf{Triple the result}: & \quad 3(x-4)\\&\textsf{Square}: & \quad [3(x-4)]^2\\&\textsf{Expand}: & \quad [3x-12]^2\\&\textsf{Simplify}:& 9x^2-72x+144\end{aligned}\)

Part (f)

The expressions are not equivalent.  

The coefficients the second equation are three times the coefficients of the first equation.

Answer:

91ft^2

Step-by-step explanation:

A = w*l

first, solve for the bottom rectangle

w = 7ft

l = 8ft

7ft * 8ft = 56ft^2

then for the second rectangle

l = 5ft

w = 7ft

5ft*7ft = 35ft^2

total area = rectangle 1+2

so 35ft^2+56ft^2=91ft^2

Answer:

The answer for the Area of the shape is 91ft²

Step-by-step explanation:

Area of the shape =Area of Bigger rectangle+ Area of small rectangle

A=L×B+l×b

A=7×8+5×7

A=56+35

A=91ft²

Answer:

  D.  1200 gallons

Step-by-step explanation:

Fractions of the total are given, as is the quantity the difference of those fractions represents. These can be used to write an equation to find the total.

Let g represent the total number of gallons of fuel sold. Then the number of gallons of 87-octane sold is 0.50g, and the number of gallons of 89-octane sold is 0.35g. The difference is said to be 180 gallons:

  0.50g -0.35g = 180

Collecting terms gives ...

  0.15g = 180

Dividing by the coefficient of g, we find ...

  g = 180/0.15 = 1200

The gas station sold 1200 gallons of fuel last weekend.

Additional comment

That's 600 gallons of 87-octane; 420 gallons of 89-octane; 120 gallons of 92-octane; and 60 gallons of 99-octane.

Answer:

3

Step-by-step explanation:

Draw a 3 part Venn diagram as shown in the picture and then add up all the ones in the purple circle as that symbolises how many times a spinner can land there:

1+1+1

= 3

The spinner has a total of 6 possible outcomes, and each outcome has a different probability of occurring. To find the probability of an outcome, we divide the number of ways that outcome can occur by the total number of possible outcomes.

The possible outcomes and their frequencies are:

2 appears once

6 appears twice

8 appears three times

Therefore, the probabilities of the different outcomes are:

P(2) = 1/6 = 0.1667 or approximately 16.67%

P(5) = 0/6 = 0 or 0%

P(6) = 2/6 = 0.3333 or approximately 33.33%

P(8) = 3/6 = 0.5 or 50%

Note that the sum of all the probabilities must equal 1, since one of the outcomes must occur. In this case, 0.1667 + 0 + 0.3333 + 0.5 = 1, so we can be confident that we have calculated the probabilities correctly.

Probability is a branch of mathematics that deals with the study of random events and their outcomes. It is concerned with predicting the likelihood of a particular event occurring based on the available information.

In probability, an event is a set of outcomes, and the probability of an event is a number between 0 and 1 that indicates the likelihood of the event occurring. A probability of 0 means that the event is impossible, while a probability of 1 means that the event is certain.

In order to calculate probabilities, we need to identify the possible outcomes of an event and determine how likely each outcome is. The sum of the probabilities of all possible outcomes must always equal 1.

In the example given, the spinner has six possible outcomes, and each outcome has a different probability of occurring. By dividing the number of ways each outcome can occur by the total number of possible outcomes, we can calculate the probability of each outcome.

Probability is used in many fields, including statistics, finance, and science. It is an important tool for decision-making and risk analysis, and it can help us to make predictions about future events based on past data.

Answer: 17

Step-by-step explanation: I did it

Answer:

12 if im correct

Step-by-step explanation:

first we have to see that they are doing 1/8 of a mile per hour so if we divide 1.48 by 1/8 it should give us the time

first we convert 1/8 to a decimal which is .125 and we divide 1.48 by .125

giving us 11.84

since it is time, 11 hrs would be too little of a time so we need to round up to 12

The number of hours for the group to clean the stretch of highway is A = 12 hours

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

In an equation, the expressions on either side of the equals sign are called the left-hand side (LHS) and the right-hand side (RHS), respectively. The equals sign (=) indicates that the two expressions have the same value, and that the equation is true for certain values of the variables involved.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. It typically consists  mathematical operations, such as addition, subtraction, multiplication, division, and exponentiation.

Given data ,

Let the number of hours be represented as A

Now , the value of A is

If the group can clean 1/8 mile of the highway in one hour, we can calculate how many sections of 1/8 mile are in 1.48 miles:

1.48 miles / (1/8 mile per section) = 11.84 sections

On simplifying the equation , we get

This means that the group will need to clean 11.84 sections of 1/8 mile each to clean the entire stretch of highway.

Since they can clean 1 section in 1 hour, it will take them 11.84 hours to clean the entire stretch of highway ≈ 12 hours

Hence , the number of hours to clean the highway is 12 hours

The value of A/B is given as follows:

A/B = -2.

From the graph, the function has a vertical asymptote at x = 1, hence the value of B is given as follows:

B = -1 -> as x + B = 0 -> x = -B = -1.

When x = 0, y = -2, hence the value of A is obtained as follows:

A/-1 = -2

A = 2.

Then the division is given as follows:
