Answer:
the answer is 12.24 .
Step-by-step explanation:
that answer is right is because when you add of those you get 530 , then you divide by how many numbers there are which is 7 , which equals to 75.7 . when you get that number ( 75.7) you subtract that number to 65,90,85,70,70,95, and 55 . when you get the total of all of those you add those . which is 10.7, 14.3 , 9.3 , 5.7 , 5.7 , 19.3 , and 20.7 . from adding those you get 85.7. you divide by 7 and get 12.24 . hope this helps :) .
 
        
             
        
        
        
Total amount of money paid
=11 x 15 
=$165
total amount of money sold
=25 x 15
=$375
difference 
= 375 - 165
=$210
        
             
        
        
        
Given:
Total length of tape in roll = 16.8 meters
Length of each piece = 1.125 meters
Number of pieces = 8
To find:
The remaining tape. 
Solution:
We have, 
Length of 1 piece = 1.125 meters
Length of 8 piece = 8 × 1.125 meters
                               = 9 meters
Total length of tape in roll = 16.8 meters
Remaining tape = Total length of tape in roll - Length of 8 piece
                            = 16.8 - 9 meters
                            = 7.8 meters
Therefore, the length of remaining tape is 7.8 meters.
 
        
             
        
        
        
Answer:
Daniel is rollerblading at 15 miles per hour
Daniel can go 3 miles in 12 minutes so we do 12÷3 to find out how many minutes it takes to go 1 mile which is 4 now we do 60÷4 to get 15
Alternatively we could do 60÷12 to get 5 then do 3×5 to get 15
Step-by-step explanation:
 
        
             
        
        
        
So normally it is
if 8x is to 6y, then how many x is to 42y?
it could be
if 8x:6y then how many x:42y or
if 8x:6y then how many y:42 x
I will solve for both
if it is
x:42y go to AAAAAAAA
if it is 
y:42x then go to BBBBBBBBBB
AAAAAAAA
 how many concerts are equal to 42 symponies
arrange in concerts to symponies format
8:6=x:42
fractionify
8/6=x/42
multiply boht sides by 42
336/6=x
56=x
56 concerts equals 42 symponies
BBBBBBBBBB
 how many  symponies are equal to 42 concerts
areange in symponies:concerts
6:8=x/42
fractionify
6/8=x/42
multiply boht sides by 42
252/8=x
31.5=x
31.5 symponies to 42 concerts
so it could be
56 concerts to 42 symponies
or
31.5 symonies to 42 concerts
