Answer:
512 inches cubed
Step-by-step explanation:
2/3 of a foot= 8in
8x8x8 or 8^3= 512
512 inches cubed
13r+23r=-2-1
36r=-3
r=-3/36
r=-1/12
Answer:
y=mx+b ( or do you mean the meaning)
Step-by-step explanation:
hope this helpssssss ?
To find the slope, use the equation of a line: 
Plug in the values for x and y:

We know that 2 can fit into 5 twice, which means 2*2 is 4.
We now have
.
If 5 is b more than 4, then this means that 4 is b less than 5. Subtract 4 from both sides, and you will have b = 1.
This means your equation is y = 2x + 1.
Yes they do form a proportion since they both simplify to 6/11
