Is terry swim three lapse in 2.5 minutes how long would it take her to swim 20 laps at the same rate
beks73 [17]
3 laps in 2.5 minutes

1 lap = 2.5/3  minute

20 laps =   (2.5/3)*20 = 16.67

20 laps ≈ 16.67 minutes

Please Help!!!

The equation looks like this:

26=x*3.5+8.50

where x is the number of pen you bought.

We solve it like this:
first, we subtract 8.50 from both sides:

17.50 =3.5*x

now we divide both sides by 3.5:
5=x

so you purchased 5 pens.
