Question

X+y/x-y если х≈10,20 у≈2,08

Answer 1

10,20+2,08 / 10,20-2,08
12,28 / 8,12
307/35 / 203/25
307/203
Отв. 307/203

Answer 2

To calculate the expression x + y / (x - y) when x ≈ 10.20 and y ≈ 2.08, simply substitute the approximate values into the expression:

x + y / (x - y) ≈ 10.20 + 2.08 / (10.20 - 2.08)

Now, perform the calculations step by step:

Step 1: Calculate the denominator (x - y)

10.20 - 2.08 = 8.12

Step 2: Calculate y / (x - y)

2.08 / 8.12 ≈ 0.2561576355 (approximated to 10 decimal places)

Step 3: Add x to the result from Step 2

10.20 + 0.2561576355 ≈ 10.4561576355 (approximated to 10 decimal places)

So, when x ≈ 10.20 and y ≈ 2.08, the value of the expression x + y / (x - y) is approximately 10.4561576355.
