Answer:
A. 11160 cubes B. 1395cm^3
Step-by-step explanation:
Volume= length x width x height
Its easiest to solve B. first and use it to solve A.
B. 7.5 x 12 x 15.5 = 1395cm^3 (volume of prism)
A. .5 x .5 x .5 = 1/8cm^3 (which is the volume of the cube)
1395 ÷ 1/8 = 11160
At first, she had +2y in the upper and -5y in the lower.
She multiplied the upper by 5 . Then she had +10y in the upper.
She should multiply the lower by 2 . Then she'll have -10y
there. She'll be able to add the two equations, and the 'y's will
go away. She'll be left with a single equation with only 'x' in it,
and she can solve that one for the value of 'x'.
The abswer i got was 93 its kinda hard to explain but im going to try my best i divide 62 by 2 got 31 so i figure to get the answer to 3 i just did 31 times 3 which is 93 i hope this helps
