Ok so:
90 + 6x - 7.5x < 30
6x - 7.5x = -1.5
90 - 1.5x < 30
-90 -90
-1.5x < -60
-60/-1.5
x=40
40 < 30
Answer:
x <= -6.33333
(>= is greater than or equal to)
(<= is less than or equal to)
Step-by-step explanation:
7 - 3(x+5) >= 11
7 - 15 - 3x >= 11
-8 - 3x >= 11
-3x >= 19
x <= 19/-3
x <= -6.33333

Answer:
1330 rounds of meetings
Step-by-step explanation:
You have a total of 21 people, and they all want to meet with each other in groups of 3. This means we are dealing with a combination problem, where combination is the selection of items in which order does <em>not</em> matter.
Formula for combination:
ₙCᵣ =
where <em>n</em> is the total number of objects (in this case, total number of people: 21), and r is the sample set (in this case, groups: 3).
We plug in and get:
->
-> 1330 different meetings for everyone to meet with each other in groups of 3.
