Abox has a mass of 1.2 kilograms. the box contains baseballs, which each have a mass of 0.15 kilogram. the total mass of the box and the baseballs is 4.8 kilograms. how many baseballs are in the box?

4.8 - 1.2 = 3.6

Divide that by 0.15 to get 24.

24 is the answer.

8(-10x+3.5y-7)

8×-10x + 8×3.5y + 8×-7

-80x + 28y - 56

therefore

-80x+28y-56 is the correct answer

4+n=5

step-by-step explanation:

this is because the four is four hours and the n represents the 1 extra hour over the weekend.

b= i'm srry i don't know that one.

4+n=5 n=1 because if vernon plays 5 hours a week then 4+1=5 hours.

hope this : )
