3
3
hours, and the second train traveled for
4
4
hours. combined, the trains traveled
625
625
miles.
if the equation
3m+4n=625
3m+4n=625
represents this situation, which statements are true regarding this equation?
select two that apply.

600,000,000,000, or 6e14

step-by-step explanation:

its a, i had the same answer, its from study island right

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
