The kaibab trail at the grand canyon begins at 7,000 feet above sea level. if you descend on the trail 4,500 feet to the colorado river and then hike up 1,375 feet to a campsite, how many feet above sea level are you?

Step-by-step explanation:

We first start at 7,000 feet above sea level, we then descend 4,500 feet closer to the sea level, therefore:

Then we go up 1,375 feet farther from the sea level, so:

step-by-step explanation:

in the absence of parentheses, i will have to make some assumptions:   i interpret your (3x+5/y^6)(4y^3/5)​ to mean:

3x + 5     4y^(3/5)       (3x + 5)(4)

* =

    y^6             1               y^(6-3/5)

if this is not what you expected, repost your question using parentheses to indicate whether you meant

4y^3

    or   4y^(3/5)

    5

step-by-step explanation:

10.50 + taxes which added up to 11.50
