Find the words Mrs.hilt read
2010 x 21 = 42210 words
Find the money of 21 books
21 x 4.95 = $103.95
I would say x=30 y=90
because
(y+x)
90+30=120
(y-x)
90-30=60
the sum of those 2 angles should equal 180 because they are supplementary angle.
120+60=180
and because the angles of 2x and y+x are also supplementary they should equal 180
2x
2(30)
=60
(y+x)
90+30
=120
120+60=180
Since the equation is lwh * 128 and we know that l = 18 and w =24
18 * 24 = 432
432 * h * 128
So, D. is the answer.
