Answer:
There were 76 childrens and 14 adults.
Step-by-step explanation:
Since the group has a total of 90 children and adults, then the sum of the number of adults with the number of children must be equal to 90 as shown below:
children + adults = 90
Since the total cost for their tickets was 548 then the number of children multiplied by the price of their ticket summed by the number of adults multiplied by the price of their ticket must be equal to that. We have:
5*children + 12*adults = 548
With these two equations we have a system of equations shown below:
children + adults = 90
5*children + 12*adults = 548
In order to solve this we will multiply the first equation by -5, and sum both equations we have:
-5*children - 5*adults = -450
5*children + 12*adults = 548
7*adults = 98
adults = 98/7 = 14
children + 14 = 90
children = 90 - 14 = 76
There were 76 childrens and 14 adults.
<u>Answer:</u>
x = -4
<u>Step-by-step explanation:</u>
We are given the following word problem which we can solve by breaking it down into parts and translating it into numerical values:
Fourteen more than three times a number is 2.
1. Fourteen more than ---> + 14
2. three times a number ---> 3x (assuming the number to be x)
3. is 2 ---> = 2
So combining these, we get:
3x + 14 = 2
Solving this to get:
3x = 2 - 14
3x = -12
x = -12/3
x = -4
4x = x + 15
