Evaluate. (w^2/x -3) ÷ 10 × z when w = -4 x = 0.8. and z = -4/5 Enter your answer as a simplified mixed number in the box.

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
