Пошаговое объяснение:

=2,15*6 6/15+(-5.5)+1 целая 7/15*2.5+11/150=43/20*96/15-5 1/2+22/15*5/2+11/150=1032/75-5 1/2+11/3+11/150=13 57/75-5 1/2+3 2/3+11/150=13 114/150-5 75/150+3 100/150+11/150=11 150/150=12

Answer 2

To solve the expression, let's substitute the given values of a, b, and c:

a = 6 + 6/15 = 6 + 2/5 = 6 2/5 = 32/5 b = -5.5 c = 2.5

Now, let's plug these values into the expression:

2(15a) + b + 1 = 2(15 * 32/5) + (-5.5) + 1

First, simplify the expression inside the parentheses:

2(15 * 32/5) = 2(480/5) = 2 * 96 = 192

Now, continue with the rest of the expression:

2(15a) + b + 1 = 192 + (-5.5) + 1

Finally, add the remaining numbers:

2(15a) + b + 1 = 192 - 5.5 + 1 = 186.5

So, the result of the expression is 186.5.
