Hey You!
16 - 20 / 16 * 100 = 25
The percentage increase from 16 to 20 is 25%. =)
Multiply 16*3 to get 48, the bike is 48 units so 16:1,16/1=16. So the answer would be 16. Hope I helped!
its none of them? 6y - 10/5 +7y = 12 10 divided by 5 equals 2
it will now look like this: 6y - 2 + 7y = 12
then your going to want to add 2 to both sides of the equation.
it will now look like this: 6y -2 + 7y + 2 = 12 + 2 = 14
simplify: 6y + 7y = 14
add the like terms: 13y = 14
