Harold wants to get at least a grade of 84 in math class. His grade will be the average of two test scores. He got a 77 on the first test.

a. Write an inequality to represent the situation.

b. What is the least grade Harold needs to get on his second test to meet his goal?

Relax

Respuesta :

The first answer is-  (77+x)/2=84

The second answer is-  Harold needs at least a 91

first, you multiply both sides by 2; 77+x=168

then you subtract 77 from both sides; x=91

then you plug it back in to check; (77+91)/2=84 ; 168/2=84 ; 84=84
