Simple...

you have -4.16-(-2.3)

but remember there's a negative in front of the (-2.3) so that gets switched into +2.3....

so now you'd have...

-4.16+2.3

=-1.86

Thus, your answer, B.

A teacher writes an inequality x divided by 6 < -2 on the board. Vincent incorrectly solves the inequality and obtains x <

scZoUnD [109]

The error Vincent made was that he only multiplied the left side of the inequality with 6 although he had to multiply on both sides

Step-by-step explanation:

Given inequality that the teacher wrote is:

$\frac{x}{6} -2$

Solving an inequality means that the variable should be isolated on left side of the inequality.

So multiplying both sides by 6

$6* \frac{2}{6} < -2 * 6\\x < -12$

Vincent got the answer is x<-2 = > The error Vincent made was that he only multiplied the left side of the inequality with 6 although he had to multiply on both sides

Hi there!

I believe your answer is:

"Add 4 to both sides, and then divide by 2. The solution is x = 12."

»»————-　★　————-««

Here’s why:

⸻⸻⸻⸻

To solve for 'x', we would have to use inverse operations.
We would first have to add four to both sides to undo the negative four. Addition is the opposite of subtraction.
We would then divide by 2 to isolate 'x'. Division is the opposite of multiplication.

⸻⸻⸻⸻

$\boxed{\text{Solving for 'x'...}}\\\\2x - 4 = 20\\------------\\\rightarrow 2x - 4 + 4 = 20 + 4\\\\\rightarrow 2x = 24\\\\\rightarrow \frac{2x=24}{2}\\\\\rightarrow \boxed{x = 12}$

⸻⸻⸻⸻

Hope this helps you. I apologize if it’s incorrect.

9x+2 (x-2) = 2 (3-x)

Feliz [49]

Alternate Forms:

13 x = 10

13 x - 10 = 0

11 x - 4 = -2 (x - 3)

Expandend Form:

11 x - 4 = 6 - 2 x

Solution:

x = 10/13
