This lesson is almost ⅔ over. Express this number as a decimal.

3 will divide 2 but since 3cannot get into 2, there will be 0. and 0 would be added to the 2 to make it 20

then 3 gets into 20 six times remainder 2 but still continues.

however, since 6 is greater than 5, it can be round down to get 0.67/0.667

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
