5x + 4x + 6x = 15x
3y - 5y + 6y - 12y = -8y
6 + 12 - 8 = 10
15x - 8y + 10

Answer:
707 feet above sea level
Step-by-step explanation:
2 hours and 25 minutes is about 2.4167 hours.
Therefore:
y=8.77x+686
y=8.77(2.4167)+686
y=21.1944+686
y=707.1944
So the hiker's elevation will be approximately 707 feet above sea level
B*h=A, where b equals the length of the base and h equals the length of the height.
3 less than twice a number x.
Twice a number would be the x multiplied by 2, and 3 less would be 3 subtracted by 2*x.
2x-3 <- The numeral form.
I hope this helps!
