Oneta writes an algebraic expression with three terms. the y-term has a coefficient of -3, and the x-term has a coefficient of 1. the expression does not have a constant term. which expression could she have written?

X - 3y + z

Another term would be the 3rd term which would be working with 3d planes instead of 2d planes.

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
