Simplify
1) -6-7(C+10)
64-7C
-76-7C**
4-13C
-16-13C
2) 5x+6(x-2) -8(x-3)
19x+36
19x+12
3x-36
3x+12
For question 2
Oops I meant to say for question 2 I got 9x-11x, so I know something went wrong there.
Question 2 is 3x+12
1. is right and 2. Simplifying
5x + 6(x + -2) + -8(x + -3)
Reorder the terms:
5x + 6(-2 + x) + -8(x + -3)
5x + (-2 * 6 + x * 6) + -8(x + -3)
5x + (-12 + 6x) + -8(x + -3)
Reorder the terms:
5x + -12 + 6x + -8(-3 + x)
5x + -12 + 6x + (-3 * -8 + x * -8)
5x + -12 + 6x + (24 + -8x)
Reorder the terms:
-12 + 24 + 5x + 6x + -8x
Combine like terms: -12 + 24 = 12
12 + 5x + 6x + -8x
Combine like terms: 5x + 6x = 11x
12 + 11x + -8x
Combine like terms: 11x + -8x = 3x
12 + 3x
did that help u
Yes that helped a lot, thank you so much Jess :D!
no problem do u need any more help with math
srry it changed my name lol but if u need more help i can see if i know the answers
yes could you tell me if these are correct?
1) r/15 is equal or more then -3
my answer was -45, is that right?
2) -8x>-64
my answer was x<8, is that right?
