1. Which is an example of the Symmetric Property? (1 point) if 3x + 2 = a + 6, then a + 6 = 3x + 2
if a = b and b = 5, then a = 5
if y = 6, then y + 12 becomes 6 + 12
x + 2 = x + 2

14. The Flower Bouquet flower shop charges $1.50 for placing an order and $0.50 for each flower ordered. Which equation could be used to find n, the number of flowers purchased if the total bill was $9. (1 point)
$9 = (0.50 + 1.50)n
0.50n + 1.50 = $9
$9 = 50n + 1.50
0.50 n + 1.50n = $9
