Answer: Length = 15, Width = 12
Step-by-step explanation:
L = length
W = width
L = W+ 3
perimeter = 2L + 2W
54 = 2(W+3) + 2W
54 = 2W + 6 + 2W
54 = 4W + 6
54 - 6 = 4W
48 = 4W
W = 
W = 12
now to find the length, plug the width into the equation L = W + 3
length:
L = W+3
L=12 +3
L = 15
I am not sure but wouldn't it be y=3x-6 and y=4x-7
Answer:
X = -6.3
Step-by-step explanation:
24 = -3 ( x - 2 ) + 3
Distributive Property
24 = -3x + 2 +3
Addition
24 = -3x + 5
Subtract 5 from each side
19 = -3x
Divide by -3 each side
-6.3 = X
(For it to be exactly 19, the answer would be -6.33333333, anywhere from only 1 three or 7 threes the answer will be 18.99
