Answer:
4in*(ft/12in)*(10lb/ft)*(16oz/lb)=53 1/3 oz
Step-by-step explanation:
Because it is at most 10, so it can be anything up to ten, since a negative times a negative is a positive, -2•-5=10, anything above -5 (-4,-3,-2, etc.) will equal less than 10

I got x=11
solution process: x-30=14-3x
-30=14-4x
-44=-4x
44=4x
11=x
