Answer:

2x = 16

16 ÷ 2 = 8

x = 8

2 + x = 28

28 - 2 = 26

x = 26

3 ÷ 6 = 0.5 (I'm not sure about this one)

27 - 10 = y

27 - 10 = 17

y = 17

1/3 = 400 cal

400 + 400 + 400 = 1, 200

whole pizza = 1,200 calories

$287 - $175 = $112

good morning :) At the carnival, the Tea cups spin at a rate of 10 rpm. How long will it take for the Tea cups to spin 43.5 time

Greeley [361]

Answer:

Option D

Step-by-step explanation:

Using Unitary Method:

10 rotations = 1 minute

=> 1 rotation = 1/10 minute

Multiplying both sides by 43.5

=> 43.5 rotation = $\frac{43.5}{10}$ minutes

=> 43.5 rotation = 4.35 minutes
