Answer:

S = 6

R = 10

Step-by-step explanation:

Givens

Let the Regular Tickets be R

Let the Senior Citizen tickets be S

Equations

85r + 24s = 994    (1)

45r + 12s = 522     (2)

Solution

Multiply equation 2 by 2

  • 2(45r + 12s = 522)
  • 90r + 24s = 1044        Subtract (1)
  • <u>85r + 24s = 994</u>
  • 5r = 50                        Divide by 5
  • 5r/5 = 50/5                 Do the division
  • r = 10

======================

Solve for s

  • 45r + 12s = 522                    Substitute r = 10
  • 45*10 + 12s= 522                 Simplify the left
  • 450 + 12s = 522                   Subtract 450  from both sides
  • 450-450 + 12s = 522-450   Simplify
  • 12S= 72                                  Divide by 12
  • 12S/12 = 72                            Do the division
  • S = 6

In the given figure, what is the measure of angle CPE?
Alina [70]

Answer:

Option B

Step-by-step explanation:

The 2 lines in this circle make a linear pair. this means that ∠CPE and ∠FPD are congruent this also means that their arcs are congruent. so you start out by setting 2x + 28 equal to 4x + 12. after you solve for x you should get x=8, inputting this into the angle equation (x + 60) and you should get 68
