364.5 because 9 to the third power is 729. 729 divided by 2 is 364.5
        
                    
             
        
        
        
Answer:
n =-19
Step-by-step explanation:
3* (n+7) = -36
Distribute
3n+21 = -36
Subtract 21 from each side
3n+21-21 = -36-21
3n = -57
Divide by 3
3n/3 = -57/3
n =-19

Answer:
f = 1
Step-by-step explanation:
Use the method of cross- multiplication
 =
 =  ⇒ ad = bc, thus
 ⇒ ad = bc, thus
20f = 5(f + 3) ← distribute
20f = 5f + 15 ( subtract 5f from both sides )
15f = 15 ( divide both sides by 15 )
f = 1
