There are 12 inches in a foot and if a yard is 3 feet then do:
3 x 12 and you get 36in
So there are 36 inches in a yard
21 friends.
44 - 2x = 2, where x is the number of friends Kristin has.
Subtract 2 on each side.
42 - 2x = 0
Add 2x on each side.
42 = 2x
Divide by 2 on each side.
42 / 2 = x
21 = x
Kristin has 21 friends.

Answer:
a ratio is a comparison of two numbers or measurements
the objects being compared are called the terms of the ratio.
if the tow terms are different units this is called a rate.
example:
David covers 600 miles in 8 hours and John covers 380 miles in 5 hours. Who is driving faster ?
solution:
Distance covered by David in 1 hour is
= 600 / 8
= 75 miles per hour
Distance covered by John in 1 hour is
= 380 / 5
= 76 miles per hour
When we compare the above unit rates (Distance covered in 1 hour), John is driving faster than David.
Answer:
Step-by-step explanation:
Solve for m
by simplifying both sides of the equation, then isolating the variable.
