The distance between city A and city B is 90 miles. Halfway between city A and city B, there is a city C. Nate started to bike from city A to city B at a rate of 12 mph, while, simultaneously Alex started to bike from city C to city B at a rate of 15 mph. Alex reached city B and turned around immediately at the same rate. At what distance from city B, did Alex and Nate meet each other?

step-by-step explanation:

ok thats very interesting

110698.56 square miles

step-by-step explanation:

multiply 3.8 by 102

387.6

multiply 2.8 by 102

285.6

multiply those two to get

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
