Answer:
20%
Step-by-step explanation:
- Start by changing the fraction to a decimal by diving the numerator by the denominator ( 1 divided by 5 ). That equals 0.2 .
- Change the decimal to a percent by multiplying it by 100% , or moving the decimal two places. That gives you 20% .
Remember, you can do anything to an equation as long as you do it to both sides
4+x-17=22
add like terms
x+4-17=22
x-13=22
add 13 to both sides
x+13-13=22+13
x+0=35
x=35
