PLEASE HELP ? Speed of pulley A=600 r. p.m.

Speed of pulleys B and C = A : 300 B:1200 C:600

Speed of pulley D = A:6 B:60 C:600

sites:

320ft

step-by-step explanation:

120 divided by 3 equals 40

40 times 4=160

160 times 2=320

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
