Here is the answer.
You just have to remember the given formula.
 
        
                    
             
        
        
        
Answer:
 m<6 = 90°
Step-by-step explanation:
If lines are perpendicular, the angles form by their intersection measure 90°.
Answer: m<6 = 90°
 
        
             
        
        
        
2m+5=5(m-7)-3m
first, use distributive property...
2m+5=5m-35-3m
next, combine like terms on the right side...
2m+5=2m-35
next, subtract 2m from both sides.
2m+5=2m-35
-2m   -2m
you will get....
5=-35 in which is not true. This means the equation has no solution.
        
                    
             
        
        
        
Answer: 
Step-by-step explanation:
 You need to convert from mixed number to decimal number. 
 In order to do this, you can follow the steps shown below: 
 1. You must divide the numerator of the fraction by the denominator of the fraction.
 2. Now you must add the quotient obtained to the Whole number part.
 Then, you get:
 
 Then, the scale image that maps "Figure A" onto "Figure B" is:
 
 Finally, in order to find the value of "x", you need to multiply the given length of the corresponding side of "Figure A" by  .
.
 Therefore, the result is:
 
 
        
             
        
        
        
9 = 2(6) - b
9 = 12 - b
-3 = b
