Using each of the digits 0-6 only once, make two equivalent ratios (proportions). There should be 6 solutions.

The answers are in bold in my Step-by-step explanation.

Step-by-step explanation:

0:0 , 0:1, 0:2 , 0:3 , 0:4 , 0:5 , 0:6

1:0, 1:1, 1:2 , 1:3 , 1:4 , 1:5 , 1:6

2:0, 2:1, 2:2 , 2:3 , 2:4 , 2:5 , 2:6

3:0, 3:1, 3:2 , 3:3 , 3:4 , 3:5 , 3:6

4:0, 4:1, 4:2 , 4:3 , 4:4 , 4:5 , 4:6

5:0, 5:1, 5:2 , 5:3 , 5:4 , 5:5 , 5:6

6:0, 6:1, 6:2 , 6:3 , 6:4 , 6:5 , 6:6

1:1 = a whole, so the others are similar.

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

a variable is any characteristics, number, or quantity that can be measured or counted. a variable may also be called a data item. hope i !
