Suzie buys a salad for $5.12 and is given $14.88 as change. which equation represents the situation if x is the amount suzie had before she bought the salad?

a. 5.12x = 14.88
b. x - 5.12 = 14.88
c. 14.88 - x = 5.12
d. x + 5.12 = 14.88

Solve this system of equations. 12x − 18y = 27 4x − 6y = 10

Solve the equation using the zero-product property. -3n(7n - 5) = 0 a. 0, -5/7 b. -1/3, -5/7 c. -1/3, 5/7 d. 0, 5/7
