Question

Тогда: найти A, B и C. Известно что: A+B=20,6; A+C=12,9; B+C=18,5?

Answer 1

Ответ:

Нет, не верно. Если а>б, а б>с, то а>с

Answer 2

Solving for A, B, and C

To solve for A, B, and C when given the equations A+B=20.6, A+C=12.9, and B+C=18.5, we can use a system of linear equations to find the values of A, B, and C.

First, let's solve for A: From the equations A+B=20.6 and A+C=12.9, we can subtract the second equation from the first to get: B - C = 20.6 - 12.9 B - C = 7.7

Now, let's solve for B: From the equations A+B=20.6 and B+C=18.5, we can subtract the second equation from the first to get: A - C = 20.6 - 18.5 A - C = 2.1

Finally, let's solve for C: From the equations A+C=12.9 and B+C=18.5, we can subtract the first equation from the second to get: B - A = 18.5 - 12.9 B - A = 5.6

Now we have a system of three equations: 1. B - C = 7.7 2. A - C = 2.1 3. B - A = 5.6

We can solve this system of equations to find the values of A, B, and C.

A = 8.5 B = 12.1 C = 4.4

These are the values of A, B, and C that satisfy the given equations.
