= 13/20
 
        
             
        
        
        
Answer:
y = 3
Step-by-step explanation:
The two inner right triangles are similar, thus the ratios of corresponding sides are equal, that is
 =
 =  ( cross- multiply )
 ( cross- multiply )
y² = 63 ( take the square root of both sides )
y =  =
 =  =
 =  ×
 ×  = 3
 = 3
 
        
                    
             
        
        
        
Answer:
32 : 12 is the second equivalent ratio. = 48 : 18 is the third equivalent ratio. Therefore, the three equivalent ratios of 8 : 3 are 16 : 6, 32 : 12 and 48 : 18
 
        
             
        
        
        
Answer:
{s | s < -8 or s >= -2}
Step-by-step explanation:
In order to solve an inequality we simply have to isolate the variable by applying the opposite operations on each side.
s - 2  <  -10   ... add 2 to both sides
s  <  -8
-3s  <=  6   ... divide both sides by -3, since we are dividing a negative number you must flip the sign
x >= -2
Therefore the final answer would be {s | s < -8 or s >= -2} which is the 3rd graphed multiple choice answer as seen attached to this answer.
