nine added to the product of 11 and a number is at most 4

Answer 1

"nine added to the product of 11 and a number is at most 4"

9 + ( 11 * x )  ≤ 4

Please note that less than or equal to ("is at most") is an inequality.

to solve:

11x + 9 ≤ 4 [expressions are usually written with variables first)

11x ≤ -5 [subtract 4 form each side retains sense of inequality]

x ≤ -5/11 [multiply by +11 retains the sense of the inequality]

Nine added to the product of (any number less than or equal to -5/11) and 11 will be less than or equal to 4.

Answer 2

Hi,

Here's how to compute the missing number.

(11XN) +9 = 4

-9 -9

---------------------

(11xN) = -5

-------- ----

11 11

N = -5

----

11

Check by replacing -5 for N.

---

11

I hope this helps. Algebra is always a step by step process, trying to get the missing number to stand alone on one side of the equation.
