Answer:

  350 inches

Step-by-step explanation:

The 7 "ratio units" represent 490 inches, so each represent 490/7 = 70 inches. Then 5 "ratio units" will represent 5×70 inches = 350 inches.

  smaller perimeter : larger perimeter

  = 5 : 7

  = (350 inches) : (490 inches)

Solve the system of equations using substitution y=x-1 and y=-2x+5
pav-90 [236]
Since the two equations equal y, set them equal to each other.

x-1=-2x+5

From there, solve for x.

First get x on one side, by using the addition property of equality.

x-1=-2x+5
3x-1=5

Isolate x by adding 1.
3x=6

Lastly get x all by itself by dividing each side by 3.
x=2

You can now substitute your x-value, 2, into one of the equations (or both, if you wish; either one will result in the same answer.)

y=x-1
y=2-1
y=1

OR

y=-2x+5
y=-2(2)+5
y=-4+5
y=1

Final answer:
x=2 and y=1
