S + g = 425
g = s + 25...these 2 equations are ur system of equations
s + (s + 25) = 425
2s + 25 = 425
2s = 425 - 25
2s = 400
s = 400/2
s = 200 <== what Seiji earned
g = s + 25
g = 200 + 25
g = 225 <=== what Gavin earned
The length of a rectangle is 12 inches more than its width. What is the width of the rectangle if the perimeter is 42 inches?
x best represents .
x + 12 best represents
1/4 x 560 = 140
the remaining 560 - 140 = 420
2/3 x 420 = 280
420 - 280 = 140 money left
