Answer:

distance between points=13 units

Step-by-step explanation:

distance between points=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

put (x_1,x_2)=(8,7) and (y_1,y_2)=(3,-5)

distance between points=\sqrt{(3-8)^2+(-5-7)^2}

distance between points=\sqrt{(-5)^2+(-12)^2}

distance between points=\sqrt{25+144}

distance between points=\sqrt{169}

distance between points=13 units answer

Kyle's family bought 4 adult tickets and 2 student tickets for $52. Maria's family bought 3 adult tickets and 5 student tickets
Troyanec [42]
Adult tickets cost $10 each and student tickets cost $6 each.

Given:
Kyle's family bought 4 adult tickets and 2 student tickets for $52
Maria's family bought 3 adult tickets and 5 student tickets for 60.

Let us assign x as the adult tickets and y as the students tickets

Kyle's family:  4x + 2y = 52
Maria's family: 3x + 5y = 60

Let us find the value of x using Kyle's equation:
4x + 2y = 52
4x         = 52 - 2y
  x         = (52 - 2y)/4
  x         = 13 - y/2
Substitute the value of x in Maria's equation to find y.
3x + 5y = 60
3(13 - y/2) + 5y = 60
39 - 3y/2 + 5y = 60
     - 3y/2 + 5y = 60 - 39
     - 3y/2 + 5y = 21
  2(-3y/2 + 5y) = 2(21)
     -3y + 10y = 42
               7y = 42
           7y/7 = 42/7
                y = 6

x = 13 - y/2
x = 13 - 6/2
x = 13 - 3
x = 10

To check:
Kyle's Family                      Maria's Family
4x + 2y = 52                        3x + 5y = 60
4(10) + 2(6) = 52                  3(10) + 5(6) = 60
40 + 12 = 52                        30 + 30 = 60
52 = 52                                 60 = 60

3k-5=20k solve the following equation for k
Virty [35]

Answer:

K = 8.3 repeating or 8 1/3

Step-by-step explanation:

3k - 5 = 20

Add 5 to the '-5' and 20 so you'll now have 3k = 25 (You're isolating the variable )

3k/3 = k

25/3 = 8.3 repeating or 8 1/3

K = 8 1/3 or 8.3 repeating.
