It is expected the spinner to land on Red 1/5 times.
<u>If the spinner is spun 40 times, then it should land on Red:</u>
<u>And it should not land on red:</u>
- (1 - 1/5)*40 = 4/5*40 = 32 times
Correct choice is D
 
        
             
        
        
        
11,340 I believe. 5% of 8400 is 420. 420*7=2940 2940+8400=11340
        
             
        
        
        
Answer:
7x -1 is correct after combining like terms
Step-by-step explanation:
6+8x-7-x 
To simplify algebraic expression we combine like terms
In the given expression
-x  or -1x  are same
8x  and -1x  are like terms
6 and -7 are also like terms
8x-1x= 7x
6 - 7 = -1
So 7x -1 is correct after combining like terms
 
        
             
        
        
        
4a+3b-(-2a-3b)
=4a+3b+2a+3b
=6a+6b
=6(a+b)
