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 is %.
Round to the nearest tenth as needed.
Thank you.

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

• Algebra 1A -

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

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

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.
