I guess that <em>d</em> is the distance you can see? Since they don't mention it in the question.
30.65 = (5/6)√h ← Divide both sides by 5/6, or multiply by 6/5
(6/5)30.65 = √h
36.78 = √h ← Square both sides to get h
h = 1352.76 or D
Answer:
We can start by rewriting the initial equation x +10y=260 in order to express how y depends on x.
This is a linear function ( it's a straight line). Linear functions have two intercepts, y and x.
To find x-intercept (also called zero of a function) we set y=0 and we solve for x.
This means that at x=260 our function has a value of 0. y(x) represents a distance from the school. This means that when y(x) is 0 our athlete reached school (finished the race), so this also answers your second question. The time it takes an athlete to finish the race is 260 minutes.
The y-intercept a value of our function at x=0. This gives us a distance of our athlete from the school at the start of the race. We find this by plugin x=0 in our equation. We get that y=26 when x=0. This makes perfect sense. Our athlete is 26 miles away from high school at the start of the race.

Answer:
1216
Step-by-step explanation:
Plug in 8 everywhere you see x.
8[(7*8)+(12*8)]
Solve, using order of operations (PEMDAS).
8(56+96)
8(152)
