Given:

The equation is

-5x-16=8

To find:

The error and correct solution.

Solution:

We have,

-5x-16=8

Add 16 on both sides.

-5x-16+16=8+16

-5x=24

Divide both sides by -5.

\dfrac{-5x}{-5}=\dfrac{24}{-5}

x=-\dfrac{24}{5}

Third step is incorrect because he divide the equation by 5 instead of -5.

Therefore, the correct solution is x=-\dfrac{24}{5}.

Is a rectangle with curved angles a polygon
Alik [6]
A polygon must have at least 3 sides, but a curved angle isn't a side. This would result in you getting an oval. In short, it would not be a polygon. Hope this helps!

Zack wants to make a profit more than $300 for painting 4 identical rooms. The profit he makes is equal to the amount he is paid
crimeas [40]
Profit = paid - supplies

Plug in the given values. We are finding out how much money he needs per room, if he is doing 4 rooms, and subtracting the supplies: 300 = 4n - 4*32.50

Simplify: 300 = 4n - 130

Add 130 to each side. 430 = 4n

Divide by 4 on each side: 107.50= n

300 = 4(107.50) - 130? True

This tells us he must be paid $107.50 to make $300 exactly. Anything larger than $107.51 and up will make more than $300.
