Length (L): 4w - 5
width (w): w
Perimeter (P) = 2L + 2w
140 = 2(4w - 5) + 2(w)
140 = 8w - 10 + 2w
140 = 10w - 10
150 = 10w
15 = w
Length (L): 4w - 5 = 4(15) - 5 = 60 - 5 = 55
Answer: width= 15meters, length=55 meters
Answer:
y=2x+7
Step-by-step explanation:
Multiply straight across:
-6 x -8 = 48
5 x 9 = 45
Simplify:
48/45 = 16/15
16/15, or 1 1/15 is your answer
hope this helps
