Question

Use the Distributive Property to solve the equation. 2/3 ​(6a+9​)=16.8

HELP ME

Answer 1

Explanation:

change 2/3 to a decimal round to the nearest tenth

.7 (6a + 9) = 16.8

.7 x 6a = 4.2a

.7 x 9 = 6.3

4.2a + 6.3 = 16.8

4.2a = 16.8 - 6.3

4.2a = 10.5

a = 10.5 / 4.2

a = 2.5

Answer 2

2.7

Explanation:

multiply 2/3 by the 6a and the 9 and you get:

4a + 6 = 16.8

move the 6 over by subtraction

4a = 10.8

divide by 4

a = 2.7
