Answer:
1/3
Step-by-step explanation:
let a = adults
so then 2a = children
a/2a(+a) = a/3a
Answer:
60
Showing-MY-Work:
4 months is 1/3 of a year. (12 months = 1 year)
Since know that they became 20, after 4 years, then we just times 20 by 3.
Because 3 times 4 = 12
20 times 3 = answer you're looking for
16x-15-9x=13
7x-15=13
+15 +15
x=4
Add 3 and 12 , cancel -2 y+2y and and add 14 and 14
3x-2y=14
12x+2y=14
15x=28
Divide both sides by 15
X=28/15
3x 28/15 -2y=14
Y=-21/5
(X,y)=28/15, -21/5
3x 28/15 -2x(-21/5)=12x 28/15 +2x(-21/5)=14
14=14=14
(x, y)=(28/15, -21/5) is the answer
Parallel lines have equal slopes, so if green line has slope = -2 then, red line's slope would be equal to -2
In short, Your Answer would be Option A
Hope this helps!
