Answer:
The weight of 6 bottles =
or 
Step-by-step explanation:
Given:
Total number of bottles = 6
Weight of each bottle =
pound
To find the total weight of 6 bottles.
Solution:
We can plot the number line for six bottles.
We can the plot the weights in another number line.
Each unit represents
pound of weight.
As the number of bottles increase the number of pounds of weight increase by
.
Thus, weight of 6 bottles =
pounds
Converting fraction to mixed number.
pounds
Or in decimals 
Thus weight of 6 bottles =
or 
Answer:
x = 10
y = 6
Step-by-step explanation:
Multiply second equation with -1 and then add it up with first equation
(-1)*(6x - 7y) = 18
-6x + 7y = -18
6x - 6y - 6x + 7y = 24 - 18 add like terms
y = 6 to find the value of x use this information
6x - 6y = 24 replace y with 6
6x - 6*6 = 24
6x - 36 = 24 add 36 to both sides
6x = 60 divide both sides by 6
x = 10
1.4 kilometers.
1401 meters - 100 centimeters = 1400 meters.
1400 meters = 1.4 kilometers.
Hope this helps!
