The symbol to show that there are parallel lines is normally just a set
of vertical lines. Although if these are being drawn on a page and need
to be labelled as part of a shape or diagram, sometimes arrows will be
used to show they are parallel - either one arrow in the middle of the
line, or two arrows to show they are parallel but in different
directions.
Answer/Step-by-step explanation:
A. Distance travelled at constant rate = 180 miles
Rate of travel (r) = distance travelled (d) /time (t)
Travel time (hrs) ==> rate of travel (miles/hr)
5 ==> 180/5 = 36
4.5 ==> 180/4.5 = 40
3 ==> 180/3 = 60
2.25 ==> 180/2.25 = 80
B. t = time travelled in hrs,
r = rate (miles/hr)
d = distance travelled = 180
Therefore, rate travelled for t hours would be:

Answer:
5 dollars
Step-by-step explanation:
multiply 100 and 1.25 and get 125 then 130 minus 125 is 5 hope this helps god bless
