Sarah is saving to buy a new phone. She needs $150, and she has already saved $63. Write an equation to model this situation. Let x represent the amount of money Sarah needs. x - 63 = 150 x + 63 = 150 x + 150 = 63 x - 150 = 63 Solve: 5 - 2x < 7. x < -1 x > -1 x < -12 x > -12 Solve: -14 10 12 42 Match the following mathematical equation to the appropriate phrase: four more than divided by 5 is 20 x the sum of and 4, divided by 5 is 20 x added to the quotient of 4 and 5 is 20 x 5 divided by plus 4 is 20 x
