Irina:
---------------------------------------------------------------------------
Irina takes 7 hours to paint the room.
In 1 hour, Irina can paint 1/7 of the room.
---------------------------------------------------------------------------
Paulo:
---------------------------------------------------------------------------
Paulo takes 6 hours to paint the room.
In 1 hour, Paulo can paint 1/6 of the room.
---------------------------------------------------------------------------
Both paint together:
---------------------------------------------------------------------------
In one hour they can paint (1/7 + 1/6) of the room.
1/7 + 1/6 = 13/42
So, it takes 13/42 of the room takes 1 hour.
---------------------------------------------------------------------------
Find the number of hours
---------------------------------------------------------------------------
13/42 of the room = 1 hour
Whole room = 1 ÷ 13/42
Whole room = 1 x 42/13
Whole room = 3.23 hours
---------------------------------------------------------------------------
Answer: They need 3.23 hours to paint the room.

Fred's age is 13 years
Let
Fred's age = x
Jack's age = 2x + 4
After 8 years:
- Fred's age = x + 8
- Jack's age = 2x + 4 + 8
= 2x + 12
Sum of their ages = Fred's age + Jack's age
59 = (x + 8) + (2x + 12)
59 = x + 8 + 2x + 12
59 = 3x + 20
59 - 20 = 3x
39 = 3x
x = 39/3
x = 13 years
Therefore, Fred's age = 13 years

So the general form followed most of the time is y=mx+b. The m represents the slope, so in this case the slope is 5.
Answer:
the answer is 12
Step 1. Perform the operations inside the parenthesis:
(4 + 9) − 3(6) ÷ 2 + 8 = 13 - 18 ÷ 2 + 8
Step 2. Division has advantage over subtraction and addition:
13 - 18 ÷ 2 + 8 = 13 - 9 + 8
Step 3. Subtract and add:
13 - 9 + 8 = 12
