Answer 6

Answer 7

you have:
(74 + x)/2 = 80
multiply both sides of this equation by 2 to get:
74 + x = 160

subtract 74 from both sides of this equation to get:
x = 160 - 74 which becomes:
x = 86
He has to get 86 on the second test to average 80 on both tests.
Assuming he gets that, then his grade average would be calculated as:
(74 + 86) / 2 = 160/2 = 80.
