1)
-1-5/6=-6/6-5/6= -11/6
2)
-27/21-7/21=-34/21
3)
-2+26/7= -14/7+26/7 =12/7
So, 30 is the perimeter. We are told the table is twice as long as it is wide.
So, we have think of 2 numbers, one being twice as big than the other. So, it is a rectangle The two number represents the length and the width. To find the perimeter we add all the lengths and the widths. Since the pool table is a rectangle we have two lengths and two widths.
So,
the tow numbers be 10 and 5. 5 is half of 10 and, when multiplied by 2 it is 10. So just to make sure the numbers 5 and 10 work out lets do a calculation.
So,
10+5+10+5 = 30feet. This proves that the sides are these two numbers.
You can spend about 3.54 per square ft.
In order to find this we will need to figure out how many square ft. there are exactly. We can do this by doing 20 x 12, which is 240. Now, to figure how much we could spend per square ft., we would have to do 850 / 240, which is(rounded) 3.54.
