Payton brought packages of black t-shirts and packages of white t-shirts. Each package of black t-shirts contains 3 shirts. Each package of white t-shirts contains 4 shirts. Payton bought b packages of black t-shirts and 5 packages of white t-shirts for total of 38 t-shirts. Which equation could Payton solve to determine the number of packages of black t-shirts, b, he brought?

A. 38 - 5(4) = b

B. 3b + 4(5) = 38

C. 38 - 3b = 5

D. 3(4) + 5b = 38

B

Step-by-step explanation

The answer is: B

Step-by-step explanation:

use the power rule  

( a b ) n = a n b n

to distribute the exponent.

apply the product rule to  

3 x 2 y 3 . ( 3 x 2 ) 2 ( y 3 ) 2

apply the product rule to  

3 x 2 . 3 2 ( x 2 ) 2 ( y 3 ) 2

raise  

3

to the power of  

2 . 9 ( x 2 ) 2 ( y 3 ) 2 multiply the exponents in   ( x 2 ) 2

.

apply the power rule and multiply exponents,  

( a m ) n = a m n . 9 x 2 ⋅ 2 ( y 3 ) 2

multiply  

2   by   2 . 9 x 4 ( y 3 ) 2

multiply the exponents in  

( y 3 ) 2 .

apply the power rule and multiply exponents,  

( a m ) n = a m n . 9 x 4 y 3

⋅

2

multiply  

3   by   2 . 9 x 4 y 6
