Using the expansion
tan(x - y) = 
, then
tan(x -

= 
→ B
New pump:
5 hours = 1 pool
1 hour = 1/5 pool
Old pump:
15h = 1 pool
1h = 1/15 pool
If both work together
1h = 1/5 + 1/15 = 4/15 pool
4/15 pool = 1 hour
1/15 pool = 1/4 hour
15/15 pool = 1/4 x 15
1 pool = 3.75 hours or 3 hours 45 mins
I tried to answer this question but I can’t find the answer
Answer:
Wilson is 6 older than mary
w=6+m
wilson is 10 less than 5 times mary
w=-10+5m
w=5m-10
so now we set them eqal to each other since both equal w
m+6=w=5m-10
m+6=5m-10
minus m both sides
6=4m-10
add 10 to both sides
16=4m
divide both sides by 4
4=m
sub back
w=m+6
w=4+6
w=10
wilson=10
mary=4
the correct method is math
