Solve the two-step equation. -0.45x + 0.33 = -0.66
What is the solution?
x = -2.2
x = -1.4
x = 1.4
x = 2.2

Step-by-step explanation:

-0.45x + 0.33 = -0.66  subtract 0.33 both sides

-0.45x = -0.66 - 0.33    simplify

-0.45x = -0.99               multiply both sides by 100

-45x = -99                   divide -45 both sides

x = -99 / -45                  simplify

x = 11/5 or 2.2

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)
