Question

3) -2 4/13 (13 - P) +1 1/13 (26 – p) пpи p = 3 1/4.​

Answer 1

Ответ:

-2 4/13(13-р)+1 1/13(26-р)= - 30+2 4/13 р+28 - 1 1/13 р=1 3/13 р - 2  

при  р=3 1/4  

1 3/13 * 3 1/4 - 2=16/13 * 13/4 - 2=4-2=2

Answer 2

To solve the expression when $p = 3 \frac{1}{4}$, we need to substitute $p$ with the given value and then perform the calculations. Let's go step by step:

Given expression: $-2\frac{4}{13}(13 - p) + 1\frac{1}{13}(26 - p)$

Step 1: Substitute $p$ with $3\frac{1}{4}$: $p = 3 \frac{1}{4} = 3.25$

Step 2: Replace $p$ in the expression: $-2\frac{4}{13}(13 - 3.25) + 1\frac{1}{13}(26 - 3.25)$

Step 3: Perform the calculations inside the parentheses: $-2\frac{4}{13}(9.75) + 1\frac{1}{13}(22.75)$

Step 4: Multiply the fractions: $-\frac{38}{13}(9.75) + \frac{29}{13}(22.75)$

Step 5: Perform the multiplications: $-\frac{38 \times 9.75}{13} + \frac{29 \times 22.75}{13}$

Step 6: Calculate the results of the multiplications: $-\frac{370.5}{13} + \frac{656.75}{13}$

Step 7: Convert both fractions to have a common denominator (13): $-\frac{370.5}{13} + \frac{656.75}{13}$

Step 8: Combine the fractions: $-\frac{370.5 + 656.75}{13}$

Step 9: Add the numerators: $-\frac{1027.25}{13}$

Step 10: Simplify the fraction (divide the numerator by the denominator): $-79.0192307692$ (rounded to 10 decimal places)

The value of the expression when $p = 3 \frac{1}{4}$ is approximately $-79.0192307692$.
