the following table shows the length and width of two rectangles:
length width
rectangle a 3x + 2 2x - 1
rectangle b x + 5 5x - 1
which expression is the result of the perimeter of rectangle b minus the perimeter of rectangle a?
2x + 2
2x + 6
22x + 14
22x + 18

16

step-by-step explanation:

2 x 40 = 80

80/5

= 16

a) at most means it can cost $12 or less

so the inequality sign would be ≤

you would then need to multiply the number of toppings by the 0.35 for each one and add it to the cost of the cheese pizza.

the equation would be 9.99 + 0.35x ≤ 12

b) using the above equation:

9.99 + 0.35x ≤ 12

subtract 9.99 from each side:

0.35x ≤2.01

divide both sides by 0.35:

x ≤ 2.01 / 0.35

x ≤5.74

at most you could have 5 toppings.

the 5 topping pizza would cost: 0.35 x 5 = 1.75 + 9.99 = $11.74
