We are given that 0<a<b, which means that 0>-a>-b if you multiply it by -1, which means what's given by our inequality is true and we are done.
The answer to this is 15 because you would multiply 5*3 to get you answer or you could do 5+5+5 either way it equals 15
4.05x+5.25(149-x)=710.25
Solve for x
X=60 ........4.05
149-60=89.....5.25
