Answer:
Then the answer is option a
a. 0<x
10
Step-by-step explanation:
perimeter + height is less than 130 inches.
If height is 60 inches.then perimeter left is 70 inches.
If perimeter was more than 70 inches then perimeter 60 more than the height would be more than 130.
perimeter of rectangle is
It has two widths and two lengths because that's what rectangles do.
width of base "x"
Then the length is 2.5x
perimeter = 2 width + 2 length
= 
= 2x + 5x
= 7x
but perimeter can't be more than 70 inches.
So x can't be more than 10 inches because if x was more than 10 inches, then 7x which is perimeter would be more than 70 inches.

7x + 60 ≤ 130
7x ≤ 70
x ≤ 10
Then the answer is option a
a. 0<x≤10
Answer:
B
Step-by-step explanation:
18 + 1.50c = $ You just make an equation then replace c with the number of toppings
Answer: See step-by-step below.
Step-by-step explanation:
First we need to solve the equation, 16x + 16x - 1 = 10.
16x + 16x - 1 = 10
32x-1 = 10
Whatever we do on one side, we have to do on the other.
So, we will add 1 to both sides.
32x - 1 + 1 = 10 + 1
Simplify.
32x = 11
x = 11/32
So, 22x = 22(11/32)
= 121/16
= 7 9/16
