The number of teams she can make is 10.
<h3>How many teams can she make?</h3>
Division is the process of putting a number into equal groups using another number. The sign used to denote division is ÷. Division is one of the basic mathematical operations. Other basic mathematical operations include addition, subtraction, multiplication.
The number of teams that can be made can be determined by dividing the total number of friends by the total number of players in each team. The whole number that is derived from the division process is the number of teams teams that can be made given the total number of friends and the number of people that have to be in each group.
Number of teams she can make = total number of friends / number of people in each group
31 / 3 = 10 remainder 1
So, only 10 teams can be made. one person would not be on any team.

Answer:
(a) $4250,
(b) $5225.
Step-by-step explanation:
Let n represent number of months.
We have been given that John saves $3500 the first month and every month later decreases it by $75.
First of all, we will find formula of John's savings in n months using arithmetic progression, where, 1st term is 3500 and common difference is 75.
, where,
n = Number of terms in a sequence,
d = Common difference.
![a_n=3500+(n-1)75](https://tex.z-dn.net/?f=a_n%3D3500%2B%28n-1%2975)
![a_n=3500+75n-75](https://tex.z-dn.net/?f=a_n%3D3500%2B75n-75)
![a_n=3425+75n](https://tex.z-dn.net/?f=a_n%3D3425%2B75n)
(a) To find John's savings in 11 months, we will substitute
in above formula.
![a_{11}=3425+75(11)](https://tex.z-dn.net/?f=a_%7B11%7D%3D3425%2B75%2811%29)
![a_{11}=3425+825](https://tex.z-dn.net/?f=a_%7B11%7D%3D3425%2B825)
![a_{11}=4250](https://tex.z-dn.net/?f=a_%7B11%7D%3D4250)
Therefore, John would have saved $4250 in the 11th month.
(b) To find John's savings after 2 years, we will substitute
in above formula.
![a_{24}=3425+75(24)](https://tex.z-dn.net/?f=a_%7B24%7D%3D3425%2B75%2824%29)
![a_{24}=3425+1800](https://tex.z-dn.net/?f=a_%7B24%7D%3D3425%2B1800)
![a_{24}=5225](https://tex.z-dn.net/?f=a_%7B24%7D%3D5225)
Therefore, John would have saved $5225 in 2 years.
Answer:
y≤-3
Step-by-step explanation:
5 - 8y ≥ 11 -6y There isn't anything to distribute
So bring the variable to one side of the inequality
In this case add 6 to both side
5 -2y ≥ 11
now subtract 5 in both side
-2y ≥ 6
now you have to divide by -2 so you have have to flip the sign since you are dividing by a negative number
y≤-3
Try to splat it up to three so ot will be easier and than add all you answers. Joke time potato \ potato
X= 30
Y=28
Step-by-step explanation:
It's a right-angle triangle. So, 3 x 30 will give you a 90 degree angle.
180-90=90
That means the next 2 angles should add to 90.
2x28=56
56+34=90
Hope this helps!
