there are 15 more girls than boys. there are 10 boys for every adult. if there are 5 adults at the disco, how many girls are there ?

First you put the words into math

girls 

x+15

boys

x  

adults

a=x/10

a=5

so first you figure out the amount of boys

swith a=x/10 plug in 5 5=x/10 and switch the ten to the other side so 5*10=x

= 50=x

so x=50

x+15 is

50+15 

whih equals 65

there are 65 girls
