Answer:

60 push-ups

Step-by-step explanation:

Set up a ratio to represent the problem:

Molly : Liza

10 : 15

40 : ?

How did we get from 10 to 40?

You multiply by 4. Therefore, multiply by 4 on both sides of the ratio.

10 : 15

x4   x4

40 : 60

svp [43]

Answer:

2 hours 11 minutes

Step-by-step explanation:

Each hour Sally can paint 1/3 rooms, Steve can paint 1/8 rooms.

If they work together, each hour they can paint 1/3 + 1/8 = 11/24 rooms.

So They will take 1/(11/24) = 24/11 = 2.18 hours to paint a whole room.

2.18 hours = 2 hours 0.18*60 minutes

0.18 * 60 = 11

Answer: 2 hours 11 minutes

Minchanka [31]
Answer:

(7 x 3) + p

Explanations:

The number of cars Toretto has = 7

The number of cars Brian has = 3

The product of Toretto and Brian Cars = 7 x 3

The product of Toretto and Brian Cars = 21

Rome has p cars more than the product of Toretto and Brian's cars

The expression for the number of cars Rome has will be:

Number of Rome's cars = (7 x 3) + p

which can also be simplified as 21 + p
