**Problem 1 : **

Solve for x :

x + 3.2 = -8.5

**Problem 2 : **

Solve for x :

30 = -0.5a

**Problem 3 : **

Solve for a :

-2/3 + y = 8

**Problem 4 : **

Solve for p :

-p/3.5 = 9.2

**Problem 5 : **

A painter works 37.5 hours one week. If he had worked 5 days, how many hours did he work on average per day ?

**Problem 6 : **

When two times of a number is divided by 7, the result is 12. Find the number.

**Problem 1 : **

Solve for x :

x + 3.2 = -8.5

**Solution : **

x + 3.2 = -8.5

Subtract 3.2 from each side.

x = -11.7

**Problem 2 : **

Solve for x :

30 = -0.5a

**Solution : **

30 = -0.5a

Divide each side by (-0.5).

-60 = a

**Problem 3 : **

Solve for a :

-2/3 + y = 8

**Solution : **

-2/3 + y = 8

Add 2/3 to each side.

y = 8 ⅔

**Problem 4 : **

Solve for p :

-p/3.5 = 9.2

**Solution : **

-p/3.5 = 9.2

Multiply each side by (-3.5).

p = -32.2

**Problem 5 : **

A painter works 37.5 hours one week. If he had worked 5 days, how many hours did he work on average per day ?

**Solution : **

Let x be the number of hours he worked per day.

Write an equation.

5x = 37.5

Divide each side by 5.

x = 7.5

So, the painter worked 7.5 hours on average per day.

**Problem 6 : **

When two times of a number is divided by 7, the result is 12. Find the number.

**Solution : **

Let x be the number of boxes.

Then,

2x/7 = 12

Multiply each side by 7/2.

x = 42

So, the number is 42.
