Abathtub is draining at a constant rate. after 2 minutes, it holds 30 gallons of water. three minutes later, it holds 12 gallons of water. write an equation that represents the number yy of gallons of water in the tub after xx minutes

d

step-by-step explanation:

i used the pitagoras theoreme

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
