Answer 3

It seems like you have an equation that needs to be solved for the value of 'x'. Let's solve it step by step:

0.8x + 0.9x = 11.05

First, combine the like terms on the left side of the equation:

(0.8x + 0.9x) = 1.7x

Now, the equation becomes:

1.7x = 11.05

To solve for 'x', you need to isolate 'x' on one side of the equation. You can do this by dividing both sides of the equation by 1.7:

(1.7x) / 1.7 = 11.05 / 1.7

x = 11.05 / 1.7

Now, calculate the value of 'x':

x ≈ 6.50

So, the solution to the equation is approximately:

x ≈ 6.50
