Write the division as a fraction
2/3x - 8 = 9
Multiply both sides of the equation by 3
2x-24=27
Move the constant to the right and change the sign
2x=27+24
Add the numbers
2x=51
Divide both sides by 2
2x/2=51/2
X= 25.5
Answer:
At 8:52:30 am they will be side-by-side again
Step-by-step explanation:
Let s be the distance ran in one 1 lap.
Here Jeff runs one extra lap compared to Mandy for coming side by side again.
Mandy runs one lap in 2 minutes and 30 seconds = 150 s
Speed of Mandy, 
Jeff runs one lap in 2 minutes and 15 seconds = 135 s
Speed of Jeff, 
Let t be the time when Jeff run one extra lap,
That is
So after 1350 seconds Jeff comes side by side to Mandy,
They both start at 8:30 am
1350 s = 22.5 minutes = 22 minutes 30 seconds
Time = 8:52:30 am
Answer:
4 s^2 / 3 r^2
Step-by-step explanation:
8 / r^3 s^2 / 6/ r s^4
8 r s^4 4 s^2
= --------- * ------- = ----------
r^3 s^2 6 3 r^2
1. I want to know what percent of the school has birthdays in the summer
2. A form with the months of the year listed, so each participant can just circle the month they were born in. I’d have pencils and a form collection box.
3. I would give the form to every fifth student to leave the cafeteria on one day. I will count up how many forms were completed and how many forms have a summer birth month circled. Then I can find the percentage of students surveyed who have summer birthdays.

I think what they’re looking for it is for you to get information that reflects a part of a larger group of students.
Statistics always wants a randomized sample, giving everyone an equal chance to be surveyed and/or represented in the survey. Getting the survey done in one day, on people leaving the cafeteria, where everybody has to go at some point in a day, and choosing every fifth person keeps you from showing any bias to who you’re surveying.
Please comment if you have questions about this, or if your teacher asks for more information.
