You can use repeated subtraction to solve 84 divided by 6 by subtracting 6 from 84 repeatedly, and stopping until either you reach zero, or until you cannot make any more groups of 6.

Answer:
x = 7
Step-by-step explanation:
The segment marked 6x is the midline of the triangle, so is half the length of the base.
6x = 1/2(84)
x = 42/6 = 7
The value of x is 7.
Take the original coordinate (x,y)
to reflect over x-axis change it to (x,-y)
*basically change the sign of y*
to translate 6 units left (x-6,y)
* basically subtract 6 from x
So your new point should be (x-6,-y)
Bruce has a rope that is 21 feet long he needs to cut the rope into 1/5 long pieces.
The length of the rope = 21 feet
the length of each strip = 
We need to cut the rope 21 feet into strips
To find the number of strips we divide 21 feet by the length of the strip
= 
= 105
105 strips can Bruce cut from his rope.
