What is the solution set of the compound inequality x + 1 < –2 x + 11 < 3 x + 5?\ 65 < x < 103
No solution
–2 < x < 103
– 13 < x < 2

Ithink the answer is a

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
