Answer:(15+6)÷3
Step-by-step explanation:
You add 15 and 6 to get the total, the divide by 3 to see how much each person pays.
<span>The answer to this question would be: A. the number of adults
</span>
In this question, there are 4 times as many students as adults going on the trip. If we put it into a function where s= student and a=adult, then we could get one equation:<span>
1. s=4a
</span><span>
Each student ticket cost $2 and each adult ticket cost $4. The total cost of the trip is $144. We also can get one equation for this
2. 2s+ 4a= 144
If you put the first equation into the second, you will get:
</span>2s+4a= 144
2(4a)+4a= 144
The function is already similar with <span>2(4x)+4x but it uses a instead of x. Then x = a = number of adult</span>
Slope formula: Change in y over change in x
Change in y: +4
Change in x: +5
Slope: 4/5
