The height of the smaller rectangle, let us say is 5
5 x 4 = 20
(multiply height of rectangle to scale factor)
the length is 4
4 x 4 = 16
(multiply length of rectangle to scale factor)
to find larger factor, divide smaller with larger
16/20 = 1/4
scale factor should be 1/4
multiply 20 with 4
perimeter of larger should be 80
hope this helps
Solve for m:
(-3 m)/7 = 12
Multiply both sides of (-3 m)/7 = 12 by -7/3:
(-7 (-3) m)/(3×7) = (-7)/3×12
(-7)/3×(-3)/7 = (-7 (-3))/(3×7):
(-7 (-3))/(3×7) m = (-7)/3×12
(-7)/3×12 = (-7×12)/3:
(-7 (-3) m)/(3×7) = (-7×12)/3
(-7)/7 = (7 (-1))/7 = -1:
(-3-1 m)/3 = (-7×12)/3
(-3)/3 = (3 (-1))/3 = -1:
--1 m = (-7×12)/3
(-1)^2 = 1:
m = (-7×12)/3
12/3 = (3×4)/3 = 4:
m = -74
-7×4 = -28:
Answer: m = -28

Circumference = πd, where d = diameter
we know the wheel has a diameter of 27 inches, so the total circumference is 27π, and that's the arc length of one revolution.
there are 5280 feet in 1 mile and 12 inches in 1 foot.
so in 40 miles there are 40(5280)(12) inches.
and we also know that there are 60 minutes in 1 hour.
