Answer:
8x+29
Step-by-step explanation:
open the brackets the collect like terms together
 
        
             
        
        
        
B;
$6.00 lb + 15%  = 6.00 x 1.15 = $6.90
$6.90 x 2.6lbs = $17.94
C;
New price is $.90 more.
3.5 x .90 = $3.15 more
        
             
        
        
        
Correct answer is B
10/15=.666
This is RW divided by RT 
Now you have to use the scale factor. Multiply by 18 to get WV
18 x 0.666 = 12 
Good Luck Thnks for brainiest :)
        
             
        
        
        
Answer:
a= 336 different ways 
b= 10 possible combinations
Step-by-step explanation:
As it is a definite machine and it must have ordered combinations therefore it is a permutation question . So finding 3 out of eight 
8 P 3= 336  different ways the eight machines be arranged in the three spaces available.
Since the parts are randomly selected and there is no distinct pattern therefore combinations is used to solve this.
5C2 = 10 possible combinations of two parts can be selected.
