Because Philip is conducting a survey that pertains to the weight of the cows, he needs statistics that directly relate to weight.
The cows being overweight doesn't give Philip concrete information on the weight of the cows, as it doesn't give the amount of pounds a cow weighs. Average age has nothing to do with weight, and normal body weight doesn't give concrete information on weight.
The answer is "<span>What is the weight of each cow on the farm?".</span>
Been a bit since i’ve done this kind of problem.
X+4=20
X is the number of hours needed to work, while 4 is the hours already there.
We can divide each digit by 7. So 56/7=8 and 21/7=3
so.... 8:3
