it's 0.4 while it may look like 4% it's actually 40% of 1
Answer:
Step-by-step explanation:
Let c represent the number of children that attended the concert.
Let a represent the number of adults that attended the concert.
At one of the concerts, each adult brought 4 children with them, and 10 children attended without an adult. This means that the number of children that attended is
c = 4a + 10
Tickets for a concert were $5 for each child and $8 for each adult. The total ticket sales were $1730. It means that
5c + 8a = 1730
Therefore, the systems of equations that can be solved to determine the number of children, c, and adults that attended the concert is
c = 4a + 10
5c + 8a = 1730
This is simple. It is 7 factorial, or 7!. This just means 7*6*5*4*3*2*1, which is 5040.
Answer:
All of the above
Step-by-step explanation:
The question is asking you which equation you can use for you to find the value of the undefined variable, n.
In this case, all of the equations above are eligible to find the value of the variable n since regardless of the variable position, you will yet be able to find its value.
