One half the sum of nine and three
Your answer

Answer:

Yes you are correct, the answer is D

Step-by-step explanation:

the answer is still 420 regardless if you do :

\(42*(3.5+1.3+5.2)\\\)

or

\((42* 3.5)+(42* 1.3)+(42 *5.2)\)

6 + 4c algebraic expression represents the phrase Six more than the product of 4 and the number of c cups.

An expression is combination of variables, numbers and operators.

We need to find the algebraic expression represents the phrase Six more than the product of 4 and the number of c cups

The phrase Six more than the product of 4 and the number of c cups" can be translated into an algebraic expression as

6 + 4c

more than in the sentence is addition and product is nothing but multiplication.

Therefore, 6 + 4c algebraic expression represents the phrase Six more than the product of 4 and the number of c cups.

Step-by-step explanation:

Answer:

y = 6x

Step-by-step explanation:

So for this we simply find a x and y coordinate (ex. (10, 60))

Since we see that the y coordinate is 6 times of the x coordinate, we know that the equation for this proportional relationship is y = 6x.

Answer:

its music not math

Step-by-step explanation:

Considering area (A) of garden as 30 square feet:

30 = x(2x+7)

Now we need to expand it:

x(2x+7) = 2x^2 + 7x

2x^2 + 7x = 30

Adding this into an Algebra calculator gives us 5/2 or 2.5

So x = 2.5

To prove this:

2(2.5) + 7 = 12

14 * 2.5 = 30

Answer: 5 coins

Step-by-step explanation:

Frank found 9 coins on the floor of his car, and 3 of them were quarters. This means that 3 out of the 9 coins, or \(\frac{3}{9}\), were quarters.

Simplifying this fraction, we get \(\frac{1}{3}\) of the coins found in the car were quarters.

If Frank finds 15 more coins on the ground at the same ratio, then \(\bold{\frac{1}{3}}\) of these coins will also be quarters. To find out how many quarters he will most likely find, we need to find \(\bold{\frac{1}{3}}\) of 15:

\(\large \frac{1}{3} \times 15 = 5\)

Therefore, Frank will most likely find 5 more quarters on the ground, assuming he finds coins at the same ratio as he did in his car.

Answer:

17

Step-by-step explanation:

We are given the equation: x=4. So, the expression turns into 1^4+2^4. 1^4=1*1*1*1, which is 1. 2^4=2*2*2*2, which is 16. Finally, 1+16 is 17, and thus we get the answer 17.

Answer:

(5^2)(n^4)

Step-by-step explanation:

since the exponents have common bases of 5, we can think of it like 4-2, since the 5^2 being in the denominator makes it negative, and since n^4 is left unaffected, we are left over with (5^2)(n^4)

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

Explanation:

We have these three rules for scale factors

With those rules in mind, we have enlargements for these transformations.

All of which represent some scale factor larger than 1. We don't have enough information to pinpoint what that scale factor would be.

In other words, if you go from small to big, then you apply some scale factor larger than 1 to enlarge the image.

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

We also have these reductions

This is where we go from big to small. The image shrinks and we use some scale factor between 0 and 1.

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

And finally we have these transformations in which the size of the image does not change. Therefore the scale factor is 1.

The order doesn't matter for this subset, but the order will matter for the other batches of transformations.

Answer:

\(10bf^{3} (2f^{3} -3b^{2} +4bf)\)

Step-by-step explanation:

\(40f^4b^2 - 30f^3b^3 +20f^6b\)

\(20bf^{6} -30b^{3} f^{3} +40b^{2} f^{4}\)

\(10bf^{3} (2f^{3} -3b^{2} +4bf)\)

This is a system of three equations with two unknowns, x and y. To solve it, we can use the method of elimination. First, we can eliminate y by subtracting the first equation from the second equation:

x^2-2y=3 - (x-2y=3) => x^2-x=0

Then we can factor the resulting equation and find the values of x:

x^2-x=0 => x(x-1)=0 => x=0 or x=1

Next, we can substitute these values of x into any of the original equations and find the corresponding values of y. For example, using the first equation:

x-2y=3 => 0-2y=3 => y=-3/2 when x=0 x-2y=3 => 1-2y=3 => y=-1 when x=1

Finally, we can substitute these values of x and y into the expression x2y-2xy2 and evaluate it:

x2y-2xy2 => 02(-3/2)-2(0)(-3/2)2 => 0 when x=0 and y=-3/2 x2y-2xy2 => 12(-1)-2(1)(-1)2 => -3 when x=1 and y=-1

Therefore, the value of x2y-2xy2 can be either 0 or -3 depending on the values of x and y.

Step-by-step explanation:

153805 is divisible by 5

The smallest number is the one closest to zero, or after zero, if it's a negative number, while the largest number is the number with the largest difference from the smallest, or the highest of value (not considering all situations). Usually, you would use the ascending order method for graphing numbers based on their value, which is indeed smallest to largest. According to thefreedictionary.com, "A function or variable continuously approaching zero as a limit." Tip: In ordering numbers based on value, the whole numbers that aren't negative are considerably believed to be the easiest numbers to order.

With that being said, here is the order of the numbers from smallest to largest:

4.38

4.5

4.6

4.9

Answer:

Here are the numbers ordered from closest to zero to farthest from zero:

4.38 (closest to zero)

4.5

-4.9 (farthest from zero)

Answer:

20 square units

Step-by-step explanation:

you can separate this irregular polygon into 2 rectangles:

Rectangle 1 (bigger): 3 Units X 4 Units = 12 square units

Rectangle 2 (smaller): 2 Units X 4 Units = 8 square units

Add the 2 areas: 12+8 square units = 20 square units

Answer:

20

Step-by-step explanation:

To get the area of this irregular polygon, we have to turn the irrelgular polygon into 2 shapes. (Imagine a line drawn from the corner/wall that separates the unit 1 and 4 units down the bottom of the shape. I don't rlly know how to explain it sorry).

First we calculate the first rectangle which is simple, you just have to multiply! 3x4= 12.

Then for the second one, we have to subtract. Basically, 8 units minus 4 units is equal to 4 units meaning that our lenght is four units. Then 3 units minus 1 unit is equal to 2 units which is our width. (i'm deeply sorry if I couldn't explain it the best) Now we just do 4x2=8.

Now we just add 12 and 8 which gives us 20!
