Answer: D) 18

Step-by-step explanation:

6 - x = -12

Subtract 6 from both sides.

-x = -18

Divide by -1 on both sides so as to isolate x.

x = 18

Answer:

D. 18

Step-by-step explanation:

The first thing you need to do is subtract 6 from both sides. This makes it cancel out on the left, since 6 - 6 = 0, and subtract 6 from -12:

6 − x = −12

-6        - 6

________

-x = -18

Then divide both sides by -1, because there's a negative sign (-) in front of the x, meaning there's like an invisible 1 there:

-1x = -18

x = 18

I’ll fail if I don’t get this right pls help
son4ous [18]

Step-by-step explanation:

In order to find the number of solutions, we have to expand both sides out first.

3(x - 2) + 7x =  \frac{1}{2} (6x - 2)

First, expand 3(x-2), which will obtain 3x-6.

Next, expand (1/2)(6x-2), which gives 3x - 1.

The result at this point should be as shown below:

3x  - 6 + 7x = 3x - 1

Now, we would shift all x terms to the left and all number terms to the right.

3x + 7x - 3x =  - 1 + 6

After simplifying, the final equation would be:

7x = 5

This is a linear equation and it has one solution.

x =  \frac{5}{7}

Clayton is at most 2 meters above sea level. Using C for Clayton, which inequality correctly represents this statement?
Nataly [62]

Answer:

C ≤ 2

Step-by-step explanation:

Given that :

Clayton is at most 2 meters above sea level ;

Let Clayton = C

Clayton's distance can be represented by the inequality :

2 meters above sea level is positive, +2

At most 2 meters above sea level means, Clayton could be anywhere between + 2 metwrs but not more than 2 meters

Hence, Clayton's distance can be represented by the inequality :

C ≤ 2
