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:
14
Step-by-step explanation:
Answer:
you just need to replace the number into x
Step-by-step explanation:
for example:
f(-4) 1+3x
=1+3(-4)
= -11
The answer should be 12.2
7^2+10^2=c^2
49+100=c^2
149=c^2
12.2=c
Answer:
11
Step-by-step explanation:
H =V/(LxW)/3
H = 297/(9x9)/3
H = 297/(81)/3
H = 297/27
H = 11
Therefore, the height of the pyramid is 11ft square
