Answer: 22.14 (22.1428571429)

Step-by-step explanation:

OK

Let's Start with the equation

0.7(x−7)−4.9=5.7

Add 4.9 to both sides

0.7(x-7)=10.6

Divide both sides by 0.7

x-7= 15. 1428571429

Add 7 to both sides

x= 22.1428571429 or 22.14

Enter the number in two equivalent froms
Vika [28.1K]

The decimal equivalent is 0.60, and the percent is 60%. If you do 3/5, you get 0.60, and to get the percentage, you move the decimal two to the right, and add the percent sign. I hope you understand. :)
