How much is 75% of 10 liters of milk?

Answer 7.5

Step-by-step explanation:

You can find this by dividing the number by 10, for example let’s use the number 20.

you would divide 20 by 10 which is 2 and times it by 7.

This is 14.

By finding this you have found 70% of 20.

now to find 5%, i would divide 20 by 10 once again which is 2 and then i would divide it by 2 which is 1.

then you would add the 2 numbers so 14+1 to get 15 therefore 75%of 20=15

8(-10x+3.5y-7)

8×-10x + 8×3.5y + 8×-7

-80x + 28y - 56

therefore

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