Answer:
94 Child tickets were sold.
Step-by-step explanation:
Let x represent child tickets
Let y represent adult tickets
Cost Equation: 5.70x + 9.75y = 1306.10
Quantity Equation: x + y = 173
Multiply the Quantity Equation by -5.70
5.70x + 9.75y = 1306.10
-5.70x - 5.70y = -986.10
4.05y = 320.00
÷4.05 ÷4.05
y = 79
x + y = 173
x + 79 = 173
x = 94
1. b. Commutative Property of Addition
Reason: There is no multiplication used
2. a. 60
Reason: 36 + 24 = 60
3. b. 3d + 9
Reason: Simplification and combining like terms :)
4. b. 4,-1
Reason: Coefficients are the numbers in front of variables
5. b. 36m + 9
Reason: Just use distributive property (multiply 9 into both terms inside parenthesis)
6. b. 95.488
Reason: b = 165.288 - 39.7 - 30.1
7. The question is cut off, unanswerable
8. c. 5a, -3a
Reason: Like terms are things you can combine. So technically the answers could be b. and c. but just go with c. because they have variables.
9. b. 16
Reason: just add 4 to both sides to get the "a" by itself
Best of luck to you!
