Tom volunteered 1 out of the last 12 days at the school store. Which shows the decimal form of this ratio?

WILL MARK BRAINLIEST!!

0.0833...

Step-by-step explanation:

1 out of 12 can be rewritten as 1 divided by 12.

1 divided by 12 is 0.08333333...

I'm not sure how many places you want to round it to, but if you were to round it to the hundredths place you would get 0.08, and if you were to round it to the thousandths place you would get 0.083.

Hope this helps!

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
