If you solve and equation and get a false statement, for example 5=2, what can you conclude about the solution

• There is no solution

• There are infinite solutions

• The solution is x = 5

• The solution is (5,2)

Given the equation 3x + 5 = -10, what would be the first step in solving this equation? What would be the solution?

• divide by 3 on both sides; x= -1

• add 5 to both sides; x = - 5/3

• subtract 3 to both sides; x = -7/5

• subtract 5 to both sides; x = -5

Solve the equation

• 11

• 3

• -13

If mass = volume times density then rearrange the formula to solve for density.

m=vd

• d = m/v

• d = v/m

• d= v * m

• d = v + m

The formula for perimeter of a square is p = 4s. How would you solve for the side length?
