Question

4.7k+5.3k-0.83 если k=0.83 8.3 0.083​

Answer 1

Ответ:

$4.7k + 5.3k - 0.83 = 10k - 0.83 \\ k = 0.83\\ 10k - 0.83 = 10 \times 0.83 - 0.83 = 8.3 - 0.83 = 7.47 \\ k = 8.3 \\ 10k - 0.83 = 10 \times 8.3 - 0.83 = 83 - 0.83 = 82.17 \\ k = 0.083 \\ 10k - 0.83 = 10 \times 0.083 - 0.83 = 0.83 - 0.83 = 0$

Answer 2

To evaluate the expression 4.7k + 5.3k - 0.83, we need to substitute the value of k with its given values: 0.83, 8.3, and 0.083. Let's calculate each case:

1. k = 0.83: Substituting k = 0.83 into the expression, we have: 4.7(0.83) + 5.3(0.83) - 0.83 = 3.881 + 4.399 - 0.83 = 7.28

2. k = 8.3: Substituting k = 8.3 into the expression, we have: 4.7(8.3) + 5.3(8.3) - 0.83 = 39.01 + 44.09 - 0.83 = 82.27

3. k = 0.083: Substituting k = 0.083 into the expression, we have: 4.7(0.083) + 5.3(0.083) - 0.83 = 0.391 + 0.441 - 0.83 = 0.002

Therefore:

• When k = 0.83, the expression evaluates to 7.28.
• When k = 8.3, the expression evaluates to 82.27.
• When k = 0.083, the expression evaluates to 0.002.
