Question

Help please I don’t know how to do this!!

Answer 1

The answer to this is / 7c -70

Answer 2

7c-70 is the Answer

first you want to do distributive property. since the -10 is on the outside of the parentheses, you multiply it by the numbers that are in the parentheses. After you do this, the equation should look like

50c-40c-70-3c

Then, you want to combine like terms. The 70 does not have a variable so you want to combine the one with exponents which are 50c,-40, and 3c

50-40 is 10. Then you would add the variable: 10c 10c-3c is 7c once all like terms are combined the equation should look like this:

7c-70

I really hope this helped you
