Solve by elimination.
multiply the lower equation by negative 1.
-y=7x-21
-y+y=o
new equation is
7x+6-52=0
6-52 is -46
-7x=-46
divide by -7
x=6.57...
plug it back in
y= 7(6.57)+21
7*6.57= 46
y=46+21
y=67
(might be wrong, I tried)
The answer is
the option A

Answer: volume inches= 12 cubic
1/4 x 16= 4
4x3 =12

I'm going to assume that you mean 56% of the calories come from fat. So, we would have to find out 56% of 270 which is 151.2, so now we know that 151.2 calories in the cereal come from fat!
2^4x-2^3x-3
2^3=2x2x2
Which equals 8
