n → smaller

20 - n → larger

4 (20 - n) = 5n - 1

80 - 4n = 5n - 1

81 = 9n

n = 9

20 - n = 11

Therefore, the numbers are 9 and 11.

Your larger number is 11 and your smaller one is 9. You solve this by first dividing 20 in half. Then you make one larger than the other by subtracting 1 from one 10 and adding adding that subtracted 1 to the other 10. Then you multiply 11 by 4 (11×4) and get 44 then multiply 9 by 5 (9×5) and get 45. Then subtract 44 from 45 (45-44) and the difference is 1.

Vaselesa [24]

Answer:

69.993

Step-by-step explanation:

Using the percentage error formula:

Percentage error = (true - measured value / true measurement ) * 100%

1% error in measurement

1% of 69.3

0.01 * 69.3 = 0.693

True measurement = error in measurement + measured value

True measurement = 0.693 + 69.3

Actual measurement = 69.993

Hence, actual measurement = 69.993.
