Kathy has three brothers: allan, age 3; George age 7; and juan; age 8. if she doubles allan age subtracts allan age from George age and add Georges age to juans age the sum of the three results equal her friend arrons age A. 18 years
B. 22 years
C. 25 years
D. 30 years​

18 years

C. 25 years

Step-by-step explanation:

From my understanding you were asking to;

Double Allan's age, which is three, so double of his age would be six

Subtract Allan's age, three, from George's age, seven, and you would get four

Add George's age, seven, to Juan's age, eight, and get fifteen

Then you asked to add all the results together which would be;

6 + 4 + 15

That would equal 25 and since we were measuring years it would be 25 years, not just 25.

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.

i can't solve unless i know what the line is
