The sum of the digits of a three-digit number is 6. The hundreds digit is twice the units digit, and the tens digit equals to th

EleoNora [17]

A+b+c=6, a=2c, b=a+c using a and b in the first equation gives you:

2c+a+c+c=6 now use a=2c again

2c+2c+c+c=6

6c=6

c=1, since a=2c

a=2, since b=a+c

b=3

So the number is 231.

The formula of a midpoint of the segment between the points

$(x_1,\ y_1),\ (x_2,\ y_2)\\\\M\left(\dfrac{x_1+x_2}{2},\ \dfrac{y_1+y_2}{2}\right)$

We have:

$(17,\ -11),\ (-14,\ -16)$

Substitute:

$M\left(\dfrac{17+(-14)}{2},\ \dfrac{-11+(-16)}{2}\right)\to M\left(\dfrac{3}{2},\ \dfrac{-27}{2}\right)$

5/8 of the 64 musicians in a music contest are guitarists. Some of the guitarists play jazz solos, and the rest play classical s

motikmotik

The first thing we must do for this case is find the number of total guitarists.

We have then:

$(\frac{5}{8}) * (64) = 40$

We now look for the relationship between the number of guitarists playing jazz alone to the total number of guitarists.

We have then:

$\frac{x}{40} = \frac{1}{4}$

Where,

x: number of guitarists playing jazz alone

From here, we clear the value of x.

$x = (\frac{1}{4}) * (40)\\x = 10$

Then, the number of guitarists who play classical solo is:

$40 - 10 = 30$

Answer:

30 guitarists play classical solos in the contest
