Answer: 
Step-by-step explanation:
Let n= Number of packs John needs.
Tiles in 1 pack = 6
Tiles in <em>n</em> pack = <em>6n</em>
If he needs at least 100 tiles.
then
 6n ≥ 100

The required inequality: 
 
        
             
        
        
        
502 and 63 have no common factors:
Factors of 63: 1, 3, 7, 9, 21, 63
Factors of 502: 1, 2, 251, 502
Therefore the simplest form of 502/63 is 502/63
        
             
        
        
        
Answer:
32
Step-by-step explanation:
This is an equilateral triangle, the 3 sides are equal.
Also, that means 3 angles are equal.
Given the 2 angles, we can say:
2x - 4 = 5y
Also, the angle is "5y" as they are equal.
Sum of 3 angles of a triangle is 180, so we can write:
2x - 4 + 5y + 5y = 180
2x + 10y - 4 = 180
2x + 10y = 184  [Equation 2]
From the first equation we can solve for y:

Now, we plug this into Equation 2 and find x:

So x is 32
 
        
             
        
        
        
1. Since 9 pages in 3 hours were read, we would find the greatest common factor (GCF) of both numbers, which is 3. So you do 9 divided by 3 (3) and 3 divided by 3 (1) which leaves you with the unit rate 3/1 or 3 pgs. p/ hr.
2. 20/4. The GCF of 20 and 4 is 4. So 20 divided by 4 is 5 and 4 divided by 4 is 1. Therefore leaving you with the unit rate 5/1 or 5 lb. p/ $.
3.  60/2. The GCF of 60 and 2 is 2. 60 divided by 2 is 30. 2 divided by 2 is 1. So the manatee can surface again in 30 seconds. 30/1 or 30 b. p/ sec.
Hope I helped! :)
