Yuliya22 [10]3 years ago
8 0

Answer:

x = -2

Step-by-step explanation:

First let's solve the given equation.

5x - 2 = -12

Combine the constants by adding 2 to both sides.

5x = -10

Isolate x by dividing both sides by 5.

x = -2

This is your answer.

Check your answer by plugging x = -2 back into the equation.

5x - 2 = -12

5(-2) - 2 = -12

-10 - 2 = -12

-12 = -12

Your answer is correct.

Hope this helps!

Write greatest unit fractions that are repeating decimals. Then express each fraction as a decimal.
LekaFEV [45]
Our repeating decimal would be= 0.5555….
Let’s give 0.5555….. repeating decimal a variable of x:
x= 0.5555…. or 0.5(move 1 point to the right)
So ,10x = 5.5555 or 5.5

Now, Let’s do subtraction:
10x = 5.5555… or 5.5  
<u>-   x =  0.5555… or 0.5</u>
 9x  = 5.0            or 5.0

To get a fraction, provide a denominator the same with the numerator of variable x which is 9. Then divide the difference:
<span><u>9x</u> = <u>5.0</u>  
9        9</span> <span> <span><span> <span> <span>Therefore, x = <u>5
</u>                                     9</span> </span> </span> </span></span>
