A: 45x + 30y = 1350
Since we don’t know how many adults and children are in the group, we use x and y
b: x-intercept= 30 y-intercept=45
To find the x-intercept you need to isolate the variable. 45x/45 = x
Then you do the same thing to the other side. 1350/45 = 30
So x=30
Same thing with the y-intercept.
30y/30 = y 1350/30 = 45
y=45 (Not really sure what it means by “what they represent” but I thinks it’s that there are 30 adult tickets and 45 children tickets )
c: so our points are (30,0) and (0,45) so you would graph that.
To find how many children tickets were bought if there were 20 adult tickets just look at the photo I put. I don’t know how to explain this.
Hope this helps

Answer:
18 jumps would be expected in a 2 hour period.
Step-by-step explanation:
Given : A dolphin jumps 54 times in a 6 hour period.
To find : At this rate, how many jumps would be expected in a 2 hour period?
Solution :
Applying unitary method,
In 6 hour period Dolphin jumps 54 times.
In 1 hour period Dolphin jumps
times.
In 1 hour period Dolphin jumps 9 times.
In 2 hour period Dolphin jumps
times.
In 2 hour period Dolphin jumps 18 times.
Therefore, 18 jumps would be expected in a 2 hour period.
Answer:
140
