"The product of a number and -8, decreased by
13 is less than or equal to 27."

less than

So you have:

-8n - 13 ≤ 27Now, solve for n:

-8n -13+13 ≤ 27 + 13-8n ≤ 40

Now, to divide both sides by a negative number (-8), you must change the inequality to ≥

-8n/-8 ≥ 40/-8n ≥ -5

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
