Solve the following inequality: –1 + 6(–1 – 3x) > –39 – 2x.
a. x < 3
b. x < –10
c. x < 2
d. x < –3

1. Collect like terms
(-1 - 39) + 6(-1 - 3x) - 2x
2. Simplify
-40 + 6(-1 - 3x) - 2x
3. Expand
-40 - 6 - 18x - 2x
4. Collect like terms
(-40 - 6) + (-18x - 2x)
5. Simplify
-46 - 20x

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
