3(x-7)+8=-20
Multiply the bracket by 3
(3)(x)(3(-7)+8= -20
3x-21+8= -20
3x-13= -20
Move -13 to the other side. Sign changes from -13 to +13.
3x-13+13= -20+13
3x= -7 
Divide by 3 
3x/3= -7/3
x= -7/3 or in mixed number : -2 1/3
Answer : x= -7/3 or in mixed number : -2 1/3
 
        
                    
             
        
        
        
Answer:
   5/12
Step-by-step explanation:
You want the tangent of angle F in right triangle FGH with sides FG=24, GH=10, and FH=26.
<h3>Tangent</h3>
The mnemonic SOH CAH TOA is intended to remind you of the relations between trig functions and the sides of a right triangle. The TOA part of this tells you ...
   Tangent = Opposite/Adjacent
<h3>Application</h3>
The side opposite angle F is GH = 10. 
The side adjacent to angle F is FG = 24. 
Then the tangent is ...
   tan(F) = GH/FG = 10/24
   tan(F) = 5/12 . . . . . reduced to lowest terms
 
        
             
        
        
        
Answer:
F. a1 = –5, an = 5an-1
Step-by-step explanation:
a1 = -5                    <---- Answer
r = -25/-5 = 5
an =  r(an - 1) 
an =  5(an - 1) <---- Answer
Hope this helps!
 
        
                    
             
        
        
        
Answer:
