Answer:
x = 5
Step-by-step explanation:
These triangles are similar, so they are in proportion to each other. Because of this we can say
(the lengths of the vertical sides) =
(the lengths of the hypotenuses). If we solve by cross-multiplying the numbers and then dividing we get x = 5.
Answer:
Each will pay $61.75.
Step-by-step explanation:
How many gallons were used?
Each 100 miles, 3 + 1/4 = 3 + 0.25 = 3.25 gallons are used. The trip has 1500 miles.
100 miles - 3.25 gallons
1500 miles - x gallons



Cost
Each gallons costs $3.80.
48.75 gallons cost 48.75*3.80 = $185.25
Split among the three friends envenly, how much will each pay?
185.25/3 = 61.75
Each will pay $61.75.
Answer=4000ft
There are 3280.84 feet in 1 kilometer
1km=3280.84ft
4000ft >3280.84 ft
therefore, 4000ft is longer than 1 km
4000ft>1km
