Answer:
   M = (S -C)/C
Step-by-step explanation:
Starting with ...
   S = C + MC
we want to solve for M.
   S - C = MC . . . . subtract the term not containing M
   (S -C)/C = M . . . . divide by the coefficient of M
Solved for M, the formula is ...
   M = (S -C)/C
 
        
             
        
        
        
Answer:
3.2t - 2.4
Step-by-step explanation:
Given
- 3.6 - 1.9t + 1.2 + 5.1t ← collect like terms
= (- 1.9t + 5.1t) + (- 3.6 + 1.2)
= 3.2t + (- 2.4)
= 3.2t - 2.4
 
        
             
        
        
        
Answer:
S12=855735
Step-by-step explanation:
if the 3rd term is 45 then,
formula: Sn=ar^n-1
S12=5*3^12-1
S12=5*3^11
S12=5*177147
S12=855735
