Josh has hiked 17 km, which is 2 km away from being 1/2 done.
<span>In a equation, this might look like: 17 + 2 = (1/2)h </span>
<span>where h is the length of the hike. </span>
<span>and solve for h, h = 38 km

Answer:
x + 2(2x-4) = 10
Step-by-step explanation:
Here in this question, we want to select which is the correct answer if we substitute for the value of y in the second equation, using the first.
In the first, we have;
y = 2x -4
Now, let’s input this value of y into the second equation.
By direct substitution, what we have is the following;
x + 2y = 10
—-> x + 2(2x -4) = 10
