Answer:
After 4 days, the number of people attending both conferences be the same.
Step-by-step explanation:
We are given the following in the question:
Maths conference:
Number of people already signed = 7
Number of people who sign up each day = 2
Thus, the number of people who will sign up for maths conference in x days will be given by the linear function:
![f(x) = 7+2x](https://tex.z-dn.net/?f=f%28x%29%20%3D%207%2B2x)
History conference:
Number of people already signed =11
Number of people who sign up each day = 1
Thus, the number of people who will sign up for maths conference in x days will be given by the linear function:
![g(x) =11+x](https://tex.z-dn.net/?f=g%28x%29%20%3D11%2Bx)
Both conference will have same number of people when
![f(x) = g(x)\\\Rightarrow 7 + 2x = 11+x\\\Rightarrow x = 4](https://tex.z-dn.net/?f=f%28x%29%20%3D%20g%28x%29%5C%5C%5CRightarrow%207%20%2B%202x%20%3D%2011%2Bx%5C%5C%5CRightarrow%20x%20%3D%204)
Thus, after 4 days, the number of people attending both conferences be the same.
Find the change
the change is 63-21=42
42 degrees in 12 hours
we want to find xdegrees/1hour
42/12=3.5 degrees per hour
p<321
The number of people the auditorium can sit is less than 321.

Problem 18)
The distance from J to L is 30 units. We can count out the number of spaces or do subtraction to get 30-0 = 30. I subtracted the number line coordinate of J and L. The result is positive as distance is never negative.
Take 2/3 of this value to get (2/3)*30 = 20 which means that we start at J and add on 20 units to get 0+20 = 20
So the final answer is 20, which is where this point is located on the number line.

Problem 19)
The distance from A to B is 3 units because |-5-(-2)| = |-5+2| = |-3| = 3
Double this value to get 2*3 = 6
Now add 6 units to the coordinate of point A to get
-5+6 = 1
The location of this point is at 1 on the number line.

Problem 20)
From J to I, or vice versa, we travel 5 units.
Multiply this by 1.5 to get 1.5*5 = 7.5
So we subtract 7.5 units from 0 (the coordinate of point J) getting us 0-7.5 = -7.5
Final Answer: -7.5
Note: this is the midpoint of -10 and -5 on the number line
