Hello!

Well, if you do not count y as a vowel, we have 5 vowels. There are 26 letters in the alphabet, plus the 9 numbers gives us 35.

As a fraction this gives us 5/35, which is equal to 1/7. As a rounded decimal, this is about 0.14.

As a percent, this is about a 14% chance of it generating a vowel.

The answer is 0.14.

Hope this helped!

Tickets for a play cost $3 for children and $10 for adults. A group of 25 people paid a total of $201 for tickets to the play. H
lidiya [134]

Answer: There were 7 children

Step-by-step explanation:

Let's use <em>x </em>to represent the children and <em>y </em>to represent the adults.

We know they combine to make a group of 25 people so x+y=25

We also know that they paid $201 and that there is $3 per child and $10 for adults so 3x+10y=201

I will solve by substitution.

Solve for y in the first equation

x+y=25\\x-x+y=25-x\\y=25-x

Sub in our value for y into the other equation and solve for x

3x+10y=201\\3x+10(25-x)=201

Step 1) Simplify

3x+250-10x=201\\-7x+250=201

Step 2) Subtract 250 from both sides

-7x+250-250=201-250\\-7x=-49

Step 3) Divide both sides by -7

\frac{-7x}{-7} =\frac{-49}{-7}\\x=7
