Nine billion, three million, eight hundred forty thousand, one hundred sixty five
Answer:
z=2
Step-by-step explanation:
2z-6=2(2+2)-10 Distribute.
2z-6=4+4-10 Combine like terms.
2z-6=-2 Add 6 on both sides.
<u>+6 +6</u>
2z=4 Divide by 2 on both sides.
<u>/2 /2</u>
z=2
Hope this helps! Have a great day ^^

Mean = (total of contributors) / (number of contributors)
For the 6 people in the room, you have
40 = (total of contributors) / 6
(total of contributors) = 6*40 = 240
A 60-year-old left the room, decreasing the total of contributors by 60.
(new total of contributors) = (total of contributors) - 60
(new total of contributors) = 240 - 60 = 180
Then the new mean is
(new mean) = (new total of contributors) / (new number of contributors)
(new mean) = 180 / 6 = 36
The mean age of the remaining 5 people is 36.
Y=-1/5x+3 the 3 would be the y intercept and the -1/5 is your slope and you would start at the 3 and use your slope and go down one and over five since it’s negative
