Alright this is gonna be a long one
Lets called child tickets x and adult tickets y
so x + y should be equal to 159 since they said that the total sum of the tickets is 159
so thats your first equation : x + y = 159
next form an equation using the prices,
5.40x + 8.70y = 1079.70
now that you have your two equations, just substitute the first into the second (you could either substitute for x or y by saying x = 159-y or that y=159-x)
Hope this helps.
Answer:
(C) 1/2
Step-by-step explanation:
If 4s is 2 more than 4t, then:
- 4s = 2+ 4t
- 4s - 4t = 2
- 4s/4 - 4t/4 = 2/4
- s - t = 1/2
(C) is the answer
The answer should be 7(x+8)
Answer D.)
Step-by-step explanation: becaues you KCF when dividing fractions
C is 0, since only multiplied by 0 will get 0, and the question defined that a and b not 0, so only c is 0
