I believe x would equal to 30.
Since 6 * 3 =18, 10 * 3 = 30.
What you do to one side, you must do to the other.
Hope I helped!

Step-by-step explanation:
x+8
substitute x value in
7+8

I think that this is a combination problem. From the given, the 8 students are taken 3 at a time. This can be solved through using the formula of combination which is C(n,r) = n!/(n-r)!r!. In this case, n is 8 while r is 3. Hence, upon substitution of the values, we have
C(8,3) = 8!/(8-3)!3!
C(8,3) = 56
There are 56 3-person teams that can be formed from the 8 students.
Answer:
15 weeks
Step-by-step explanation:
Let the number of weeks = x.
At the end of x weeks,
Jeremy has 120 + 14x,

We want to know when their amounts are equal.
120 + 14x = 180 + 10x
4x = 60
x = 15
