Determine the total number of adult and student tickets

There were 5 adult tickets and 3 student tickets.

Step-by-step explanation:

Step 1:

Assume the number of adult tickets purchased is x and the number of student tickets purchased is y.

From the given data, we can write the following equations;

, take this as equation 1.

Since 8 tickets were purchased,

, take this as equation 2.

Step 2:

We rearrange equation 2 so we can substitute in equation 1.

, take this as equation 3.

By substituting equation 3 in equation 1, we get

Step 3:

Substituting this value of x in any of the previous equations we will get y's value.

Here this value of y is substituted in equation 2.

So we have x = 5 and y = 3. So there were 5 adult tickets and 3 student tickets.

the answer is d. 75%

10.416 meters per second

step-by-step explanation:

distance=1 00 meters

time= 9.6 seconds in decimal form or 9 3/5 as a mixed number

average speed= 100/9.6

=10.416 meters per second or 10 52/125 as a mixed number.
