Given:
Admission to the local movie theater is $3 for each child and $7 for each adult.
A group of 12 people pay $64 admission.
To find:
The number of children in a group.
Solution:
Let the number of children be x and number of adults be y.
According to the question,
Total persons : 
...(i)
Total cost : 
...(ii)
Multiply equation (i) by 7 and subtract the result from (ii).
Divide both sides by -4.
Therefore, the number of children is 5.
So each of Colise vases have 15 roses in them so she has a total of 30 roses 20 red and 10 yellow. Michelle also has 30 roses but he has three vases, each with 6 red roses, 6 x 3 is 18 and 30 - 18 is 12, 12/3 is 4 so Michelle would have 4 yellow roses in each of her vases.
Answer:
O C. 0
Step-by-step explanation:
What is the sum of 15 and its additive inverse?
In Mathematics, the additive inverse of a number is defined as the number that when it is added to a specific number equals 0
From the above question, the additive of 15 = -15
Therefore, the sum of 15 and its additive inverse is calculated as:
15 + -15
= 15 - 15
= 0
Therefore, Option C is the correct option
