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

The answer is B. 12 x 48 = 576 and 576 / 4 = 144

i'm pretty sure it's c. nvm

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
