It’s to prove of the pounds and the congress to put each three out
X-13=42
x is the "variable", you're taking 13 away from that, and the answer is also given, 42.
So its
1/3 divided by 6/1
we get the reciprocal
1/3*1/6
so thats 1/18 for each sports team
Answer
Find out the conversion factor for seconds to minutes and convert 135 seconds to minutes.
To prove
1 minute = 60 second
for seconds to minutes.

Therefore the conversion factor for seconds to minutes be

Now convert 135 seconds to minutes.

= 2.25 minutes
Hence proved
Yes; this is a linear function because you plug in a number and multiply it by two, so the function would be y=2x, which is linear despite the fact that it lacks a b value.
Hope this helps! :)
