Answer 2

a) Let's substitute the given values into the expression:

436:x + 8.02:y - 73.2:R + 50.8:20, if x = 100, y = 2, R = 30

436/100 + 8.02/2 - 73.2/30 + 50.8/20

4.36 + 4.01 - 2.44 + 2.54

The result is 8.47.

b) Let's substitute the given values into the expression:

(81.3 - 65.2):a + (4.72 - b) * 3 : c, if a = 10, b = 2.24, c = 0.8

(81.3 - 65.2)/10 + (4.72 - 2.24) * 3 / 0.8

16.1/10 + 2.48 * 3 / 0.8

1.61 + 7.44 / 0.8

1.61 + 9.3

The result is 10.91.
