Use the distributive property to write an expression that is equivalent to each given property.

-3 (2x-4)

0.1 (-90+50a)

-7 (-x-9)

4/5 (10y-x+-15)

-6x+12

-9+5a

7x+63

8y-4/5x-12

Step-by-step explanation:

To solve these all you have to do is take the number outside of the parenthesis and multiply them by each term.

-3 (2x) - 3 (-4) All I did here was expand the problem to show what i mean by terms.

-6x+12

Do this for each problem.

0.1 (-90) + 0.1 (50a)

-9+5a

-7 (-x) - 7 (-9) For this one you are taking negatives times negatives so each answer will be positive.

7x+63

4/5 (10y) + 4/5 (-x) + 4/5 (-15)

8y-4/5x-12
