-7x ≥ 56.
Divide both sides by -7, and the inequality sign reverses, because we are dividing by a negative number.
The sign also reverses when you multiply both sides of inequality by a negative number.
-7x/-7 ≤ 56/-7
x ≤ -8
The answer is the first option.
<span>{x | x ≤ -8}
</span>
This simply means x, such that x is less than or equal to -8.
I hope this helped.

Hi there!
Pretty much, more means to add, so when you said, "10 more than 36", we immediately think addition. :)
36 + 10 = 46, right?
So, your answer is 46 :)
Hope this helps!

I am sorry but it is just an example !
Question ) A university has 30,330 students. In a random sample of 270 students, 18 speak three or more languages. Predict the number of students at the university who speak three or more languages.
Answer ) 2,022 students will speak three or more languages
Here's why:
Using proportions.
18. x
--- =. ----
270. 30,330
Cross multiply
18 x 30,330 = 545,940
270 multiply x = 270x
545,940 divided by 270 = 2,022
x = 2,022 students
