 5 (3m+2p) -4m= 15m +10p -4m
=11m +10p
--------------------------------------------------------
13p+11m-3p=10p -11m
-----------------------------------------------------------
Yes, 5 (3m+2p) -4m is  equivalent to the expression 13p+11m-3p as i worked out for you.. Hope this helps you!!! =')
        
                    
             
        
        
        
Answer:
The first term is 42.
Step-by-step explanation:
The common difference is 142  - 140 = 2 so we have
50th term =  a1 + 2(50 -1) = 140    where a1 is the first term
a1 + 98 = 140
a1 = 140 - 98 =  42.
 
        
             
        
        
        
21 cars, 32 motorcycles.create a system of equations using x for cars and y for motorcycles.

multiply the top equation by 2 to prepare for elimination method

subtract terms

divide both sides by negative 2 to solve for x
x =21
plug in x  into original equation to solve for y.
21 + y = 53
subtract both sides by 21
y=32
