System of equations will be important here. We have two pieces of information: how many tickets were sold, and the total price.

A= adults, S = students

A + S = 155 (# of tickets)
7A + 3S = 645 (total profit)

S = 155 - A , based on the first equation

Now substitute S into the second equation.

7A + 3(155 - A) = 645

7A + 465 - 3A = 645

4A = 180

180/4 = 45 adult tickets sold.

Complementary angles are two angles that have measures with a sum of 90°. Angles P and Q are complementary and the measure of angle P is 6° more than twice the measure of angle Q.



Write a system of equations and use substitution to find the measures of angles P and Q.

Input Field 1 of 1

Answers

Answer:

P = 62°   Q = 28°

Step-by-step explanation:

Let x = measure of angle Q

then y = measure of angle P

Now  x + y = 90  and 2x + 6 = y

Substituting 2x + 6 from the second equation in for y in the first equation, we get x + 2x + 6 = 90 since the two angles are complementary.

3x + 6 = 90

3x = 84

x = 28

y = 2(28) + 6 = 56 + 6 = 62

Check:  28 + 62 = 90
