Answer:
<h2>x = 5</h2>
Step-by-step explanation:

The answer to number 1 is C. Not sure how to get that, I just got it off line converting it with a website.
The answer to number 2 in B, also got that offline by converting it.
3.) Area of a circle:
Radius-16
16×16×3.14=803.84 rounded to the nearest number is 804.
Since this says ESTIMATED we look for the closest answer to 804.
The answer is C. 805 square meters. hope it helps!!!!!!!!!!!!!!!

everything is black :/
Step-by-step explanations:
Hey, here it is: 2,4 x 10^-6
To find equivalent inequalities you have to work the inequality given.
The first step is transpose on of sides to have an expression in one side and zero in the other side:
x - 6 x + 7
--------- ≥ --------
x + 5 x + 3
=>
x - 6 x + 7
--------- - -------- ≥ 0
x + 5 x + 3
=>
(x - 6) (x + 3) - (x + 7) (x + 5)
--------------------------------------- ≥ 0
(x + 5) (x + 3)
=>
x^2 - 3x - 18 - x^2 - 12x - 35
--------------------------------------- ≥ 0
(x + 5) (x + 3)
15x + 53
- ------------------- ≥ 0
(x + 5) (x + 3)
That is an equivalent inequality. Sure you can arrange it to find many other equivalent inequalities. That is why you should include the list of choices. Anyway from this point it should be pretty straigth to arrange the terms until making the equivalent as per the options.
