4 friends evenly dividing up a n - slice pizza
So each one get
slices of pizza.
For example, if n = 12 slice then each friend gets 12/4 = 3 pieces. If Harris ate one slice less then he ate
=3 -1 = 2 pieces.
So the general expression for slices of pizza did Harris eat is

In order to have average 80 score from 5 tests, student needs to have 400 points (80%*500=0.8*500=400)
So far he has 63+72+88+91= 314
400-314=86
He needs to get 86 points from the last test.
Since he is obviously getting better at tests, i think he'll manage :)

One of the angle of the triangle is 90 degrees which means it is a right angled triangle. Two angles are same i.e 45 degrees which means the angle is an isosceles triangle.
so, x = 17 (isosceles triangle)
then use pythagoreas theorem:

and x = 17, so simplify and

so
