Answer 2

To calculate the value of the expression 29а + 3в + 4с when а = 0.2, в = -5.4, and с = 6.2, you simply substitute these values into the expression and perform the arithmetic.

Let's calculate it step-by-step:

1. Replace а with 0.2
2. Replace в with -5.4
3. Replace с with 6.2
4. Perform the arithmetic

Now, let's calculate:

29а + 3в + 4с = 29(0.2) + 3(-5.4) + 4(6.2)

29(0.2) = 5.8 3(-5.4) = -16.2 4(6.2) = 24.8

Now, add up the values:

5.8 - 16.2 + 24.8 = 14.4

So, when а = 0.2, в = -5.4, and с = 6.2, the value of the expression 29а + 3в + 4с is 14.4.
