Why is partitioning a directed line segment into a ratio of 1:3 not the same as finding One-third the length of the directed line segment? The ratio given is part to whole, but fractions compare part to part. The ratio given is part to part. The total number of parts in the whole is 3 – 1 = 2. The ratio given is part to part. The total number of parts in the whole is 1 + 3 = 4. The ratio given is part to whole, but the associated fraction is One-third.

step-by-step explanation:

cause it equals more

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
