The answer is A: 13,204 more
If you take all those and add it together and subtract it, it comes out to 13,204.
4s + 3p = 85.50......multiply by 3
3s + 5p = 115.........multiply by -4
----------------
12s + 9p = 256.50 (result of multiplying by 3)
-12s - 20p = -460 (result of multiplying by -4)
---------------add
-11p = - 203.50
p = -203.50 / -11
p = 18.50 <=== the cost of a pair of pants
3s + 5p = 115
3s + 5(18.5) = 115
3s + 92.50 = 115
3s = 115 - 92.50
3s = 22.50
s = 22.50/3
s = 7.50 <=== the cost of each shirt
100 times 35=3500 she can go 3500 miles on the free gas. she can go round trip to see her cousin on free gas because 1650+1650 is less than 3500
Answer:
It will take them 5 hours to meet if they start moving towards eachother simultaneusly.
Step-by-step explanation:
Distance, s = 540 miles
Motocycle's speed, v = 48 mph
Time for motorcycle to cover 48 miles, t = 
=
= 11.25 h
For a car it takes 2.25 hours less than 11.25 for motorcycle:
Time for car than becomes: 11.25 - 2.25 = 9 h
Speed for car would be v(c) = 
=
= 60 mph
<em>For finding when they will meet, we will need relative speed: </em>
Since they are moving towards each other the relative speed is the sum of speed of car and the speed of motorcycle
Relative Speed = 48 + 60 = 108 mph
Distance = 540 miles
Time = 
= 
= 5 hours
