April pays a dog-walking service $30 each week to walk her dog Let w = the number of weeks.
Let d = the number of dollars April pays the service,
Part A
Which equation represents the problem?
A. d = W + 30
BW= d x 30
O
C. W = 30 + d
D. d = w x 30
Part B
Drag numbers to complete the table to show the number of dollars, d, that April spends on dog-walking in v

Step-by-step explanation:

d = 30 * w

The best answer is D.  One or two of the others are impossible to read.

B is an incomplete question.

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
