Answer:
A can paint in 3days and B in 6 days
Step-by-step explanation:
From the question we were told
Person A can paint the neighbors house 2 times as fast as Person B
Let A only paint the neighbors house in X days
Let B only paint the neighbors house in 2X days
If we express the given information from the question in terms of fraction we have,
1/X + 1/2X = 1/2
3/2X = 1/2
if we cross multiply we have
6= 2X
X= 6/2
X= 3
Then A can paint the house in 3 days and B in 2(3)= 6days.
-8-n=-6n+12
+8. +8
-n=-6n+20
+6n +6n
5n=20
5. 5
n=4
80 would be the answer i guess can you explain more in depth?
