Answer 3

To calculate the expression 4а + 5в - а + 3в with а = 3.5 and в = 1.7, we need to substitute the values of а and в into the expression and then perform the arithmetic operations.

Let's do the calculations step by step:

Step 1: Substitute the values of а and в into the expression: 4(3.5) + 5(1.7) - 3.5 + 3(1.7)

Step 2: Perform the multiplications: 14 + 8.5 - 3.5 + 5.1

Step 3: Perform the additions and subtractions: (14 + 8.5) - (3.5 - 5.1) 22.5 - (-1.6) 22.5 + 1.6

Step 4: The final result: 24.1

So, when а = 3.5 and в = 1.7, the value of the expression 4а + 5в - а + 3в is 24.1.
