Answer:
x=9
y=15
Step-by-step explanation:
Its a parallel gram, so the sides would be the same as the parallel side,
it is b.9 because u have to multiply (w×h×l)/3
Okay this equation really says is what is 30% of 248.
So, lets convert 30% to a fraction, 3/10 which is easier to work with.
All you have to do now is get out a calculator and do 248 *3/10 (or .3) and get 74.4
So subtract 74.4 and get
173.6
Kyle leaves 1.80 because you have to do 0.15*12
20 x 18 x 5= 1,800
20 times 18 equals 360, then you mutiply 5 and get 1,800
