Answer:
(y - 2647.7) = 39.95(x - 6)
y - 264.7 = 39.95x - 239.7
y = 39.95x - 239.7 + 264.7
y = 39.95x + 25
Answer:
23.04
Step-by-step explanation:
length×width
4.8×4.8
correct me if im wrong:)
Assume the longer piece is x feet long,
Then the other piece is 0.5x feet long
In total: x + 0.5x = 66 -> x = 44
So the longer piece is 44 feet, shorter piece is 22 feet
Answer:
x = 6, y =3
Step-by-step explanation:
4x-7y=3
x-7y=-15
Multiply the first equation by -1
-4x+7y=-3
Then add this to the second equation to eliminate y
-4x+7y=-3
x-7y=-15
------------------
-3x +0y = -18
-3x = -18
Divide by -3
-3x/-3 = -18/-3
x = 6
Now find y
x -7y = -15
6 -7y = -15
Subtract 6 from each side
6-7y-6 = -15-6
-7y = -21
Divide by -7
-7y/-7 = -21/-7
y =3
