Over the weekend koko spent 2 hours on an assignment and she spent an equal amounts of time on studying for 4 exams for a total of 16 hours how much time did ahe spend for each exam

3.5 hr per exam

Step-by-step explanation:

Hello,

Let's have x represent hours for each exam. The equation is:

2+4x=16

Subtract 2 from both sides and divide by 4 and we get:

x=3.5 hours for each exam

Make sense?

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

step-by-step explanation:

answer: 2x + 2 − 2 = 10 − 2; subtraction property of equality
