Answer:
She sell <u>2.075 kilograms</u> of pears at the farmer's market.
Step-by-step explanation:
<u><em>There is a mistake in the question some data is missing, so the correct question is below: </em></u>
<em>A farmer sells 8.3 kg of apples and pears at the farmer's market. 3 /4 of this weight is apples, and the rest is pears. How many kilograms of pears did she sell at the farmer's market?</em>
Now, to find the kilograms of pears.
Total weight of apples and pears = 8.3 kg.
Weight of apples = of 8.3 kg.
So, to get the weight of apples:
Thus, the weight of apples = 6.225 kg.
Now, to get the weight of pears we subtract the weight of apples from the total weight of apples and pears:
Therefore, she sell 2.075 kilograms of pears at the farmer's market.
Actually, the answer is not A, if you're saying A is the first choice above. That's incorrect. You will need to use the Geometric mean for right triangles here to figure out what the value of a is. We will use this form: 
. We have a value for YZ of 3; side a is XZ. That means in order to solve this we need WZ, which we can find using pythagorean's theorem. 3^2 + 4^2 = c^2 and 9 + 16 = c^2 and c = 5. Now we fill in accordingly: 
. Cross-multiply to get 3XZ=25 and side XZ is 
. XZ is 25/3 and YZ is 3, so 25/3 - 3 = XY. That means that XY (side a) = 16/3 or 5 1/3, choice B, or the second one down.
