Well if you're talking about decimals it will come out as 00.020
After 1 hour they are only 35 miles apart. After 5 minutes they are only 12 miles apart. Then after 2 they intercept.
8x + 17 = 12x -5
Solve for x
move the variable to one side
8x + 17 = 12x -5
-8x -8x
17 = 4x - 5
+5 +5
22 = 4x
______
4
5.5 = x
then substitute that value into the equation
8(x) + 17 + 12(x) -5 = ?
The answer is C. I solved for the first variable in one of the equations then substitute the result into the other equation.
