3x = 15 - 2x
x = 9
x = 3
x = -3
x = 6
−3(1+6r)=14−r
(a)
Write the equation for the model.
3x + x = -x - 3x
-x + 1 = 3x - 3
3x + 1 = -x - 3
Write the equation for the model.
2x + 7 = -3x + 2
2x - 2 = 3x - 7
2x + 2 = -3x + 7
x = 10
x = 5
x = 3
x = -3
The Frederick County Fair costs $15.00 to get in and $2.50 per ride, while the Montgomery County Fair costs $10.00 to get in and $3.00 per ride. Which equations could be used to determine how many rides you would need to go on for both fairs to be of equal value?
15x + 2.5 = 10x + 3
15 - 2.5x = 10 - 3x
15 + 2.5x = 10 + 3x
15 - 10 = 2.5x + 3x
Which situation best represents the following equation?
25 + .05x = 50 + .01x
