The formula W= 0.3x + 46.6 models the average number of hours worked by
American workers per week when W is the hours worked and x is the number of
years since 1980. When will we average 55 hours per week?

Substitute 55 for W

The average American is probably working 55 hours per week now, 28 years after 1980.

Einstein’s formula E = mc2, relates energy
and mass with the speed of light. E
represents energy in ergs, m represents
mass in grams, and c is the speed of light in
centimeters per second. The speed of light
in a vacuum is 3 × 1010 meters per second.
The square of 3 × 1010 is 9 × 1020 . 1 gram
of matter will contain 9 × 1020 ergs of
energy. The energy in 1 gram of matter
could move another gram of matter
559,234,073,013,000 miles at a rate of 1
centimeter per second.

Solve the equation E = mc2 for m.

Solve the equation E = mc2 for c2.

P= 2l+2w is the formula for calculating the perimeter of a
rectangle. l represents the length of a side of the rectangle and
w represents the width.

Solve P= 2l+2wfor w.

Add 2 to both sides

Multiply both sides by

Solve the equation 3x + 7y = 21 for x Solve the equation 3x + 7y = 21 for y
   
Subtract 7y from both sides Subtract 3x from both sides
   
3x + 7y – 7y = 21 – 7y 3x – 3x + 7y = 21 – 3x
   
3x = 21 – 7y 7y = 21 – 3x
   
Divide both sides by 3 Divide both sides by 7
   

The distance a car will travel is calculated with the formula d= rt,
where d is the distance traveled, r is the rate of travel and t is the
time traveling.

How far will the car travel at a rate of 75 miles per hour in 3
hours?

How long will the it take the car to travel 175 miles at a rate of 75
miles per hour?

How fast was the car traveling if it went 390 miles in 5 hours?

Solve the equation 3x+ 6 = 3(x+ 5) Solve the equation -2x+ 5x–18 = -3x + 6(x–3)
   
Distribute Distribute
   
3x+ 6 = 3x+ 15 –2x+ 5x–18 = –3x + 6x–18
   
Subtract3xfrom both sides Combine like terms
   
6 = 15 3x–18 = 3x –18
This is never true. There is no
solution
. This is a contradiction.
This is always true. There are infinitely
many solutions . This is an identity.
