Which values of a and b make the following equation true? a = 11, b = 7 a = 11, b = 10 a = 28, b = 7 a = 28, b = 10
xz_007 [3.2K]

Answer:

The answer is

<h2>a = 11, b = 7</h2>

Step-by-step explanation:

( {5x}^{7}  {y}^{2} )( { - 4x}^{4}  {y}^{5} ) =  - 20 {x}^{a}  {y}^{b}

Multiply the terms on the left side of the equation

That's

- 20 {x}^{11}  {y}^{7}  =  - 20 {x}^{a}  {y}^{b}

Since the bases are the same we can equate the exponents

That's

{x}^{11}  =  {x}^{a}

a = 11

And

{y}^{7}  =  {y}^{b}

b = 11

Therefore

a = 11 and b = 7

Hope this helps you

15 feet out of 36 feet
mars1129 [50]

Answer:

15/36 or 0.41666666666 or 41.6 percent

Step-by-step explanation:

Not sure if you're looking for the fraction or something else but to find the fraction, divide 15 by 36.

15/36

The decimal you get is 0.41666666666.

This converts to a percentage of 41.6 percent. (multiply by 100 to get percent when dealing with decimals)

So 15 feet is 41.6 percent of 36.

Hope this helped.
