Answer:
m = y/x
Step-by-step explanation:
y-y = m(x-x)
simplify:
-2y = m(-2x)
simplify again
-2y = -2mx
divide to get rid of -2 and x
-2y = -2mx
----------------
-2x
y
- = m
x

Given:
1 mile = 5280 feet
1 meter = 3.3 feet
convert 60 miles per hour to meters per second
60 miles to meters
60 miles x <u>5280ft</u> x <u>1meter</u> = (60*5280m)/3.3 = 316800m/3.3
1 mile 3.3ft
= 96,000 meters
1 hour to seconds
1 hour x <u>60 minutes</u> x <u>60 seconds</u> = 1 * 60 * 60sec = 3600 seconds
1 hour 1 minute
unit rate: meters per second
96000 meters ÷ 3600 seconds = 26 2400/3600
simplify 26 2400/3600 ⇒ 26 2/3 meters per second
2400 ÷ 1200 = 2
3600 ÷ 1200 = 3
Answer:
An expression for the perimeter of the square as a product using the expression for the length of one side .
Step-by-step explanation:
Given : The perimeter of a square is represented by the expression feet.
To find : Write an expression for the perimeter of the square as a product using the expression for the length of one side ?
Solution :
We know that the perimeter of the square is 4 times the side of square.
The perimeter of a square is represented by the expression feet.
Divide the expression by 4,
So, the perimeter is also written as with length of side
Therefore, an expression for the perimeter of the square as a product using the expression for the length of one side .
