Set up an equation. You know the age of April is x, then Jeanie's age would be x + 5, since she is older.

anonymous · Answer

So X+5=41
I got C?

alekos · Answer

J + A = 41
J = A +5

alekos · Answer

now substitute the second equation into the first and solve for Aprils age

anonymous · Answer

So this is how i did it. 
A+5=41
A+5-5=41-5
A=36

tyteen4a03 · Answer

@victoria_lion No, J = A + 5, so the equation is (A + 5) + A = 41.

alekos · Answer

so then 2A = 36

alekos · Answer

do you follow?

anonymous · Answer

Well tell me how c is not the answer @tyteen4a03 ?

tyteen4a03 · Answer

@victoria_lion Because your equation is not correct. See my and @alekos 's explanation above.

alekos · Answer

without using any algebra you can just take each option given, add 5, and then add the two numbers obtained.

alekos · Answer

so if we take option A we have 18 + (18+5) = 41, the total of their ages

anonymous · Answer

Omg okay thats what i was missing i forgot to add their ages *face palm*

alekos · Answer

and using algebra we also have 2A = 36  so A = 18

alekos · Answer

i'm glad it clicked

anonymous · Answer

Do you mind helping me on one last problem?

alekos · Answer

yeah sure

anonymous · Answer

thanks The graph below illustrates 2 intersecting lines. If a new line is drawn so that it passes through the red line at y = 0 and the blue line at x = –1, what is the slope of the new line? http://media.education2020.com/evresources/2003-09-02-00-00_files/i0320000.jpg

alekos · Answer

the two points in question are (-4,0) and (-1,-2) 
so the new line goes through these points

happy with that?

anonymous · Answer

Haha the way you say i feel stupid XD but yes i am. Ur awesome thanks

anonymous · Answer
