Пошаговое объяснение:

15/17b -6/17b +8/17b=1 2/9+2 7/9

17/17b=3 9/9

b=4

Answer 2

To solve the equation for b, we can combine like terms on the left side of the equation and then isolate b. Here's how you can do it step by step:

Given equation:

(15/17)b - (6/17)b + (8/17)b = 1

Combine the b terms on the left side:

(15/17 - 6/17 + 8/17)b = 1

Now, simplify the coefficients of 'b' inside the parentheses:

(17/17)b = 1

Since 17/17 is equal to 1, we have:

1b = 1

Now, simply:

b = 1

So, the solution to the equation is b = 1.

Now, let's address the second part of your question:

2 2/9 + 2 7/9

To add these two mixed numbers, first, add the whole numbers together:

2 + 2 = 4

Now, add the fractions:

2/9 + 7/9 = (2 + 7)/9 = 9/9 = 1 (since 9/9 is equal to 1)

So, the sum of 2 2/9 and 2 7/9 is:

4 1/9
