PART 4 - Mathematical Knowledge Question 5 of 5
If 2x = 16, then 3x =

24

Step-by-step explanation:

Lets do math:

2x=16 right?

then whats x?

guess to find x u have to divide both sides by two because of pemdas and other math

we get x=8

now look, if we wanna find 3x and x=8 what do we do?

h maybe we multiply 8 by 3.

that would b

24 and thats our answer.

24

Step-by-step explanation:

2x = 16 --> 2x/2 = 16/2 --> x=8

--> 3x=8*3=24

--> 24

6 equilateral triangles

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
