Why learn this:
- Linear equations cannot tell you the future, but they can give you a good idea of what to expect so you can plan ahead. How long will it take you to fill your swimming pool? How much money will you earn during summer break? What are the quantities you need for your favorite recipe to make enough for all your friends?
- Linear equations explain some of the relationships between what we know and what we want to know and can help us solve a wide range of problems we might encounter in our everyday lives.

- Linear equations with one unknown
The main application of linear equations is solving problems in which an unknown variable, usually (but not always) x, is dependent on a known constant.
We solve linear equations by isolating the unknown variable on one side of the equation and simplifying the rest of the equation. When simplifying, anything that is done to one side of the equation must also be done to the other.
An equation of:

 in which  and
 and  are the constants and
 are the constants and   is the unknown variable, is a typical linear equation with one unknown. To solve for
 is the unknown variable, is a typical linear equation with one unknown. To solve for  in this example, we would first isolate it by subtracting
 in this example, we would first isolate it by subtracting  from both sides of the equation. We would then divide both sides of the equation by
 from both sides of the equation. We would then divide both sides of the equation by  resulting in an answer of:

In a positively skewed distribution, the extreme scores are larger, thus the mean is larger than the median. Since the mean is 122, the only possible median is 118. Therefore, D.

Answer:
You can use a calculator to find all the tan, sin, cos values! Simply enter the number, for example, 52, then press the tan button! For question d, you are finding what number that decimal is the tangent of. Press the 2nd function on your calculator, and you can see that -1 beside the tan. Enter the decimal then use that button to find the reverse tangent. 
tan52 = 1.2799
sin19 = 0.3256
cos34 = 0.8290
tan-1(0.9876) = 44.6426
To solve the conveyor belt problem, you'll have to use the sine of 15. (remember, sine = opposite/hypotenuse). Set up an equation:
sin15 = ?/12m
Use a calculator to find sin15, then you can solve it like algebra. 
sin15 = ?/12m
sin15*12m = ?
0.2588*12m = ?
3.1056m = ?
Hope this helped :)
