Here is how to work the problems and write the expressions.
-5+7/ 0+ 5 = 2/5x
plug in
Y= 2/5(5) -3
Y = (5,-1) intercept
Multiply the numerator together and the denominators together.
1 x 5 / 6 . 7 = 5/42
42 is not a multiple of 5 so the answer is already in the lowest term.
The answer is 5/42
9 is 0.34 away from 9.34
8 is 1.34 away from 9.34
7 is 2.34 away from 9.34
6 is 3.34 away from 9.34
So A.)9.00
is the closest decimal to 9.34
