X 20 30 40 50 y 40 50 60 70

Which equation represents the data in the table

y = x + 20

y = 2x

x = y + 20

x = 2y

the ratio would be 4: 3, the four being for jackson, and the three being not for him.

we can set up an equation to find the girls' ages. the equation is         28=0.5x-5+x. (comment if you need me to explain how i got this equation.) so, you add x and 0.5x to get 1.5x and add 5 to each side. your new equation is 33=1.5x. now divide both sides of the equation by 1.5 to get 22=x. because x is mary's age, to find jasmine's age we subtract mary's age from 28. we find that mary is 22 years old and jasmine is 6 years old.
