Answer:

x=3

Step-by-step explanation:

You can solve by:

5x+7=-3x-31

adding 3x to each side:

8x+7=31

Subtract 7 from each side:

8x=24

Divide each side by 8:

x=3

That is your answer

Hope this helps!

Answer: x=3

Step-by-step explanation:

5x+7=-3x31

5x+7-7=3x+31-7

subtract the numbers

5x=-3x+24

add 3x to both sides

5x=-3x+24

5x+3x=3x+24+3x

combine like terms

8x=24

divide both sides of the equation by the same term 8x=24

8x/8 = 24/8

cancel terms that are in both numerator and denominator

divide the numbers

x=3

11/21 as a decimal and a percent
pochemuha

11/21 written as a decimal would be 0.52381 and in percent, it would be 52.381%.

To solve percent, since the total or 1/1 is 100%, we have to remember that the answer is less than 100%. So, we move 2 decimal places right to make it into percent. Then, the answer is 52.381.

To solve percent, you would do 100/21. Then, you would get 4.7619047619. You multiply that by 11 and get 52.381. But, you have to move 2 places left since fractions are tens, hundreds. So, you would get 0.52381.
