You multiply 8 by 1 because if you round up it will be an estimate
8 x 1 = 8
So Kim is wrong
Horse = 10
Horseshoe = 4
Boots = 2
1+10*2 = 21
Simply divide 18 by 2, which means...
John's wages are proportional, and the unit rate is 9 dollars per hour.
It is important to note that the perimeter is equal to 2(width) + 2(length). let's call width w and length L.
so 294 = 2w + 2L
but the length is two times the width, so L=2w.
294 = 2w + 2(2w)
294 = 2w + 4w
294 = 6w
divide both sides by 6 to solve for w.
49 = w. so our width is 49 feet.
L = 2w, so L = 2(49). L = 98.
our length is 98 feet.
