Answer:
its answer is the same as the top, s³+12
Well first, you have to put them together.
5X - 2 = 4X + 2 Then we have to combine like terms.
X = 0 Now we have solved for X. Hope this helped!
-Twix
10 yards per 5min is
10yrd/5min
first convert it into yards per minute
10yrds/5min = 2yrds/1min
let's first so the yards to feet part first
1 yrd = 3 feet
2yrds/min * 3ft/1yrd
so now we have
6yrds/min
now convert minute to hour
1 hour = 60 mins
6yrds/min * 60min/1hr
=360/1hr
remember so that units cancel
The answer is 13..................
