Answer 2

1. 754/58 = 559/x

To solve this equation, we can cross-multiply:

754 * x = 58 * 559

x = (58 * 559) / 754

x ≈ 42.97 (rounded to two decimal places)

So, the approximate value of x is 42.97.

2. 243/x = 30/103

Cross-multiplying:

30 * x = 243 * 103

x = (243 * 103) / 30

x ≈ 834.9 (rounded to one decimal place)

So, the approximate value of x is 834.9.

3. 715/65 = 352/x

Cross-multiplying:

715 * x = 65 * 352

x = (65 * 352) / 715

x ≈ 32.02 (rounded to two decimal places)

So, the approximate value of x is 32.02.

4. 42/14 = x/845

Cross-multiplying:

42 * 845 = 14 * x

x = (42 * 845) / 14

x = 2535

So, the value of x is 2535.

5. 480/x = 270/546

Cross-multiplying:

270 * x = 480 * 546

x = (480 * 546) / 270

x = 972

So, the value of x is 972.

6. x/65 = 270/547

Cross-multiplying:

270 * 65 = x * 547

x = (270 * 65) / 547

x ≈ 32.16 (rounded to two decimal places)

So, the approximate value of x is 32.16.

7. x/19 = 935/85

Cross-multiplying:

935 * 19 = 85 * x

x = (935 * 19) / 85

x ≈ 209.59 (rounded to two decimal places)

So, the approximate value of x is 209.59.

Please note that these answers are rounded to the specified decimal places and may not be exact.
