Answer:
Step-by-step explanation:

First let's multiply the 1st equation by 10.

So, we can see that the equations have the same coefficients and that implies they are equal.
So the equation has no solutions for. 
Answer:
Length x Width x Height
Step-by-step explanation:
Answer:
11 1/4
Step-by-step explanation:
9/2/4/10
9/2/2/5
9/2*5/2
45/4
11 1/4
-7 = 1 + 2/3n
Subtract 1 from both sides:
-8 = 2/3n
Multiply both sides by 3:
-24 = 2n
Divide both sides by 2:
N= -12
