Let x = blank
25 + 5x = 35
5x = 35 - 25
5x = 10
x = 10/5
x = 2
Done!
        
             
        
        
        
Answer:11
Step-by-step explanation:
so that is easy it is rise over run!!! 
y2-y1 over x2-x1!!! look at picture!!!
 
        
             
        
        
        
Answer:
Figure A - hexagon 
Figure B - triangle
Figure C - rectangle
Figure D - octagon 
Step-by-step explanation:
If figure B has 3 vertices (angles), then that means it is a triangle (3 sides)
So that means figure A has 6 sides, (hexagon)
And figure D has 8 vertices, so 8 sides (octagon)
And if C has half as many, that would be 4 (rectangle)
 
        
             
        
        
        
We need the total count of persons = 10+12+12+15 = 49 persons
We need the count of the target group, female or teaching assistants
= (10+12) professors + 12 male teaching assistants
= 22+12
= 34 persons
Assuming equal probability of choosing anyone from the 30 persons, the
probability of choosing a professor or a male
= 34/49
(For probability calculations, try to keep a fraction for as long as you can, because fractions are exact. Decimal are frequently approximate, for example in this case, 34/49=0.693877551020...... = 0.694 approximately)
 
        
             
        
        
        
The answer is x = -3 / 2.
