Hello!

<u><em>Answer: x=-9 *The answer must have negative sign*</em></u>

Explanation:

First you had to do is subtract by 4 from both sides of an equation.

$4-4x-4=40-4$

Then, simplify.

$-4x=36$

Divide by -4 both sides of an equation.

$\frac{-4x}{-4}= \frac{36}{-4}$

Finally simplify.

$36/4=9$

It change positive to negative sign.

$x=-9$

Hope this helps!

Thanks!

Have a great day!

What is 1.83 repeating as a fraction?

maks197457 [2]

The answer to this question would be: 1 5/6

To change a decimal number into fraction, you need to divide the number on the right of decimal point with 1. In this case, the number is 0.83.
This number is hard since .83 doesn't have many factors. To find the answer you can try to multiply the decimal with some number until it close to 1(no decimal left)
0.83* 2= 1.66
0.83* 3= 2.49 ---> close to half, if you find this number, you can try to double it
0.83* 4= 3.32
0.83* 5= 4.15
0.83* 6= 4.98---> close to 1, that means there is high probability that the number can be divided by 6
0.83 would be 4.98/6, but if we assume that the number is 0.8333...... then 0.83 would be 5/6. So, 1.83 would be 1 5/6
