X=6y
sum of their reciprocals
(1/x)+(1/y)=7
x=6y
1/6y+1/y=7
1/6y+6/6y=7
7/6y=7
times both sides by 6y
7=42y
divide both sides by 42
1/6=y
x=6y
x=6(1/6)
x=6/6
x=1
the numbers are 1 and 1/6
N3Y+7 can have infinate solutions
False if that's what you're asking
Every cm on the map = 8/2 = 4 km
so 16 cm is equivalent to 4*16 = 64 km Answer
