Then, distance of route passes the beach = x

Let the distance of route that passes the park = x+2

So, their sum would be: x+x+2 = 2x+2

So, option C Is your answer.......

Answer: First and Fourth options are correct.

Step-by-step explanation:

Let the route to the store that passes the beach be 'x' miles.

According to question, the route to the store that passes the beach is 2 miles shorter than the route to the store that passes the park.

So, the route to the store that passes the park be 'x+2' miles.

So, the length of each route would be

'x' and 'x+2' miles respectively.

Hence, First and Fourth options are correct.

Speed of truck= x

A loaded moving truck is traveling 30 mph faster than a freight train. in the time it takes the train to travel 135 miles, the truck travels 225 miles. find the speed of the truck.

A loaded moving truck is traveling 30 mph faster than a freight train...
(x-30)=speed of train
the time it takes the train to travel 135 miles, the truck travels 225 miles...
135/(x-30)=225/x
the you multiply on both sides the x values and get...
 135x=225x-6750
then you subtract 225x on both sides...
-90x=-6750
then you divide -90 on both sides...
x=75
the speed of the truck is 75mph
i hope this helped give me a thanks and a 5 star rating if it helped! c:

Zarrin [17]

22% liked neither.

Step-by-step explanation:

Given,

64% liked pop music.

52% liked rap music.

38% liked both type of music.

To find out the percentage of those liked neither.

Now,

Let, total number of student = 100

Number of students liked pop = 64

Number of students liked rap = 52

Number of students liked both = 38

So,

Number of students who liked only pop = 64-38 = 26

Number of students who liked only rap = 52-38 = 14

Hence,

Number of students who liked neither = 100 - (26+14+38) = 22

22% liked neither.
