Question

4(1.5c+6)-2c=-9 I need a help my teacher doesn't help

Answer 1

Ok 4(1.5c + 6) - 2c = -9 First u do distributive property, and if u put arrows pointing from the number outside the parenthesis to each of the numbers inside u remember easier according to my math teacher. So 4 times 1.5c is 6c then 4 times 6 is 24 Now the problem is written: 6c + 24 - 2c = -9 Now u add/subtract like terms so 6c - 2c is 4c So 4c + 24 = -9 Subtract 24 from both sides: 4c = -33 And now u just have to dived both sides by 4 to isolate the c And remember a negative times a positive is a negative (my math teacher taught us: bad things that happen to good people is a bad thing, to remember it) So the answer is: C = -8.25 Now that it is corrected, I hope that helps :)

Answer 2

4(1.5c+6)-2c=-9 so we distribute the 4 to 1.5 tand 6 and it will now be broken into this ==>   6c+24-2c=-9 ok now we most combine like terms so the we do 6c-2c= 4c so the problem is now 24-4c=-9 ok now i think we need to solve for c so we subtract 24 to -9  because it is negative it is now -33 so the problem is -4c=-33 divide by -4 and you will get your answer. I hope this helped and is correct.
