Question

Which value of x satisfies the equation 7/3 (x + 9/28) = 20?

1) 8.25
2) 8.89
3) 19.25
4) 44.92

Answer 1

8.25

Explanation:

Plug in 8.25 where x is. Then according to PEMDAS you add everything up in the parenthesis then multiply the sum of that by 7/3.

Answer 2

1) 8.25

Explanation:

multiply 7/3 with x and 9/28

7/3x + 3/4 = 20

subtract 3/4 from both sides

7/3x= 77/4

divide by 7/3 on each side

x= 8.25
