There are no given choices so I can't exactly answer this question. However, I can tell you the form of the probable answer to the choices that you have. When two variables have a direct relationship, the general formula would be: y = kx, where k is a constant. In this problem, the independent variable is number of hours, say t, so x= t. Consequently, y = earnings, say E. So, the answer would probably have the form of: E = kt, where k could be any real number.
Answer:
1. Communitave property
2. communitave property
3.
1. distribute 2 to x and 10 to get ride of parenthesis
2. subtract 2x from the left to move it to the right so x is by itself
3. add 15 to both sides to cancel it out on one side, and move to the other.
4. divide by 5 on both sides so you can get the value of x
5. flip equation so it is in the x equals form
4.
1. distribute 2 to the x and positive 3 on the left side, also distribute -4 to both x and -1 , to get rid of our parenthesis.
2. add 4x to both sides so it cancels out on one side and moves to the other ( our xs and numbers need to be on opposite sides)
3. subtract 4 on the left side to move it to the right side because again numbers on the right and letters on the left
4. divide by 6 on both sides of the equation to solve for x
