(PLEASE HELP WITH QUESTIONS 11 AND 12) 11. If AC = 3x+1 and DE = 8, find x and AC.

12. Find DE if AC = 34.

Explanation:

Just gotta fill it out so if AC is 34

34 - 1 = 3x+1 - 1  (subtract 1 from both sides)

33/3   3x/3     x=11

and DE is already there!

nswer: a   y-axis

step-by-step explanation:

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
