Look at the question below

D) The balloon

Explanation:

Ignore the "above sea level" and "below sea level" portions. Focus purely on the numbers themselves. The largest value is the furthest away from sea level. The smallest value is closest to sea level.

Therefore, the balloon is furthest from sea level because 27 is the largest of the four values (5, 12, 18, 27).

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
