From a base elevation of 8200 ft. a mountain peak in colorado rises to a summit elevation of 14588 ft. over a horizonal distance of 15842 ft. find the grade of the peak.
The grade of the peak.
The grade of the peak is %.
Round to the nearest tenth as needed.
Someone help please!!
Thank you.

Don,
X+3y= 6 find the slope m=3 I'm I correct

MathMate,
To calculate the slope, calculate the
rise (vertical) = 14588  8200 ft
run (horizontal) = 15842 ft
The slope is rise/run, convert to 100%.

Don,
Determine whether 7.5 is a soultion for the inequality.X>5. i chose yes I'm I correct

MathMate,
You're correct, but draw them on the number line to make sure you understand the answer.
∞+0+5+7.5+∞
Numbers on the right are greater than the numbers on the left. So if 7.5 is situated on the right of 5, then it is greater than 5.

Don,
Solve, 5X>45. The correct solution is
X[X>9 I'm I correct or close to it

MathMate,
Yes, it's correct, I think you got the hang of it.
How about
43x>16 ?
