The garden club wants to buy 48 rose bushes for 4 city parks. each rose bush costs $12. each park gets the same number of rose bushes how much will the rose bushes for each park cost? which number sentences show how to solve the problem?
a. 12 ÷ 3 = 4 and 48 × 4 = 192
b. 12 × 48 = 576 and 576 ÷ 4 = 144
c. 48 ÷ 12 = 4 and 48 × 4 = 192
d. 48 ÷ 4 = 12 and 12 × 12 = 144

Arrange the steps to solve this system of linear equations in the correct sequence. x + y = -2 2x – 3y = -9 tiles subtract 3x + 3y = -6 (obtained in step 1) from 2x – 3y = -9 (given) to solve for x. substitute the value of x in the first equation (x + y = -2) to get y = 1. the solution for the system of equations is (-3, 1). x = -15 the solution for the system of equations is (-15, 13). add 3x + 3y = -6 (obtained in step 1) to 2x – 3y = -9 (given), and solve for x. x = -3 substitute the value of x in the first equation (x + y = -2) to get y = 13. multiply the first equation by 3: 3(x + y) = 3(-2) 3x + 3y = -6.
