Will make simplify the expression -|4 + 3 - 8| 1 -1 15 -15 2) solve the following equation: |5x| = 20 -20, 20 -4, 4 4, 20 -4, 20

The first one is -1.
The second one is -4,4
hope this helps!

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

The answer is 90 % because since 20 multiplied by 5 is 100 you would have to do each question multiplied by 5 so 18 times 5 equals ninety percent.
