Answer:
L = 15, W = 8
Step-by-step explanation:
Perimeter = 2(L + W)
P = 40
L = 2W - 1
40 = 2((2W-1) + W)
40 = 4W - 2 + 2W
40 = 6W - 2
42 = 6W
W = 8
Since L = 2W - 1
L = 2(8) - 1
L = 15

Answer:
a 97- (55+80) +250
b Melanie has $212 left in her bank account.
Step-by-step explanation:
55 + 80 = 135
97 - 135 = -38
-38 +250 = 212
y=2X-5 and 4X-Y=7
Putting the value of Y in 2nd equation:
4x-2x+5=7
2x=7-5
2x=2
OR,x=2/2=1
putting the value of x in equation 1:
y=2x-5
y=2*1-5
y=2-5
y=-3
