Answer:
x=-1, y=8
Step-by-step explanation:
The given system is
-x+y =7
6x+y=14
We make y the subject in the first equation to get:
y=x+7
We put y=x+7 into 6x+y=14 to obtain
6x+x=14-7
7x=7
x=1
We now put x=1 into y=x+7
The solution is x=1, y=8
Part B
We now verify
-1+8=7 ....True
6(1)+8=14....True
To find volume, multiply length x width x height.
4 1/2 x 5 x 3 1/4
4.5 x 5 x 3.25 = 73.125
1/4 = 0.25
Divide the total of the large cube to the small cube.
73.125/0.25 = 292.5
292 and 1/2 of the small cube(s) are needed to fill the right rectangular prism.
hope this helps
