Answer:
20 percent or 2/10
Step-by-step explanation:
to make into a percentage it would be easy because of it being out of 100 so make the 100 a percentage and then see how much the 20 would be it would be the same 20/100 only in percentage form so 20 percent
You need to simplify the expression and then you will know what the y coordinates are. I’m not good at this But you just need to solve the equation to be able to get the same coordinates by themselves. It’s sorta like geometry and algebra mixed. But first simplify the equations and then that will really help you.
Have a great day!
