Answer:
3n+7=16
Step-by-step explanation:
3(3)+7=16
9+7=16
16=16
The second one is wrong(x=18)
First you have to get the number on the right 40 to equal 100 so do 40x2=80- +40x1.5= 100
Then do the same thing to the first number 8 so 8x2=16+8x1.5=20
then you have 20/100 right so then that number over 100 is the percent that you get ^-^ 20%
