Question

2) (4,86-0,6bc-1,5bd):(0,3b);​

Answer 1

Ответ: (4,86-0,6bc-1,5bd) : (0,3b)

(243/50-3/5bc-3/2bd) / (3/10b)

(243-30bc-75bd)/50 / 3b/10

(3*(81-10bc-25bd))/50 * 10/3b

(81-10bc-25bd)/5 * 1/b

(81-10bc-25bd)/5b

Answer 2

To simplify the expression (4.86 - 0.6bc - 1.5bd) divided by (0.3b), you can follow these steps:

1. Factor out the common term '0.3b' from the numerator:

   (4.86 - 0.6bc - 1.5bd) / (0.3b) = (0.3b * (16.2 - 2bc - 5bd)) / (0.3b)

2. Cancel out the common term '0.3b' in the numerator and denominator:

   (0.3b * (16.2 - 2bc - 5bd)) / (0.3b) = (16.2 - 2bc - 5bd)

So, the simplified expression is:

16.2 - 2bc - 5bd
