During the Memorial High School highway clean-up project, Ms. Palkowski cleaned 0.125 of a mile for the teachers' team and
then 0.4 of a mile for the science club. How much did she clean
altogether?

the answer is 13 cm

step-by-step explanation:

for volume, add base x height x width

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

7x7=4 so if u carry the 9 it will be 33
