Answer:
x=7 , y = 8.
Step-by-step explanation:
10x+65 = 135
or, 10x = 70
so, x = 7
Now,
4y-4=28
or, 4y = 32
so, y = 8
I think you divide 1/2 by -2/5 and then add that to -1/4....
Answer:

Answer:
177 and 178
Step-by-step explanation:
First, the expression for the 2nd mile marker is x+1.
Now, you add x and x + 1 together to get 2x + 1
Next, make 2x + 1 equal to 355
Now subtract 1 and then divide by two on both sides to get x = 177.
This means that the first mile marker is 177 and the next is 178.
