Answer:

B

Step-by-step explanation:

Let the nickels = x

Let the dimes = y

You don't know the total value of either. Nor do you know the total number of either.

You only know the total value of both together.

7.80 added to anything makes it bigger than 7.80 A is wrong.

y cannot be alone it should be multiplied by 0.5    C is wrong

D is wrong for the same reason A is

B is the correct answer. That is the way you write the problem

The distances of a port from 20 differ- ent locations form an AP. If the farthest distance is 300 km, and the nearest distance i
Mkey [24]

Answer:

Required difference = 270/19 km

Step-by-step explanation:

If we consider the AP of distances to be

a, a + r, a + 2r, ..., a + 19r,

where a is the distance of the nearest location from the port and r is the difference between any two successive location.

Given that,

a + 19r = 300 .....(1)

a = 30 ..... (2)

Using (2), from (1), we get

30 + 19r = 300

or, 19r = 300 - 30

or, 19r = 270

or, r = 270/19

Therefore the distance between any two successive location is 270/19 km.
