5s-100-2s=4s-20-2s
3s-100. = 2s-20
 +20. +20
3s-80. = 2s
-3s. -3s
 -80. = -1s
 -1 -1
 80. = s
s=80
        
             
        
        
        
A. 1/4; 2/4=1/2; 1/4
b. 1
c. 3/4. There are 4 blocks and 3 are not red
d. 1/4+3/4= 4/4=1
        
             
        
        
        
No he is not correct .
Break apart the number 8,184
You will get
8000 + 100 + 80 + 4 
The numbers we are comparing are 8000 and 80
80 x 10 = 800
The number we are looking for is 8000
This makes the claim that one 8 is 10 times greater false as it is in fact 100 times as great. 
        
                    
             
        
        
        
Answer:
Solution one is correct and solution 2 and 3 are incorrect
Step-by-step explanation:
You simply make an equation because for vertical angles 2 angles that are across from each other have the same value (in this case 2x+30 and 5x-36.)
The equation: 2x+30=5x-36---->3x=66----> x=22
Solution 1 is correct.
Hope this helped!
 
        
                    
             
        
        
        
Answer:
y=x-8 and y=-x+4
Step-by-step explanation:
The slopes of the lines can be anything, as long as they are the opposite reciprocals of each other. Then you can plug in the point for x and y to solve for b in both lines (for y=mx+b where m is the slope)
