Question

Distribute, then combine like terms 1/2 (12 + 10z) - 15 i need help please

Answer 1

5z - 9

Explanation:

Distributive property mean you will multiply everything in parentheses by what is on the outside of the parentheses. 1/2 x 12 and 1/2 x 10z

1/2(12 + 10z) - 15

6 + 5z - 15

Now combine like terms. There are only two like terms 6 and -15. 5z is not a like term because it has the variable.

5z - 9
