Answer:
Step-by-step explanation:
4x = 38
x= 38/ 4
x = 9 1/2
I’m pretty sure you would have a 72% which would be a low C but maybe still passing. My schools passing grade is 70%. You would have to see what a passing grade is in your school.
Using the Pythagorean theorem:
c = sqrt(8^2 + 7^2)
c = sqrt(64 + 49)
c = sqrt(113)
c = 10.6
First you find 4/5 of 8 and then 4/5of 7 and multiply them
