4 friends evenly divided up a n- slice pizza. One of the friends , Harris, ate 1 fewer slice than he received. How many slices o

4 friends evenly dividing up a n - slice pizza

So each one get $\frac{n}{4}$ 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 $\frac{12}{4}-1$ =3 -1 = 2 pieces.

So the general expression for slices of pizza did Harris eat is

$\frac{n}{4}-1$

The length of a rectangular floor is 2 feet more than its width. The area of the floor is 168 square feet. Kim wants to use a ru

ioda

Let width of the floor be x feet, them area is
x(x+2) = 168
x^2 + 2x - 168 = 0
(x - 12)(x + 14) - 0
so x = 12
the floor is 12 ft by 10 ft

the width of the rug should be 10 - 2(2) = 6 feet
