Maths- Directions
A person moves towards north a distance 20m from point P and reaches at Q. He turns 135 degrees in clockwise direction and goes 40√2m. From here he turns 135 degrees clockwise and goes 25m. How far is he now from his initial position? (If you could, could you explain ...

I would just set it up as a proportion and cross multiply. 68/2=110/? or 2/68=?/110

Distribute the 15 through the parentheses in order to get 15x-45 first.

The absolute value bars just mean that what is inside of them must be positive because the distance from zero on a number line is always positive.

See above.

If you don't like fractions, then clear them by multiplying each thing by 12. Otherwise, just add fractions with a common denominator like with arithmetic.

There are many ways to do this, but what I would like to do here is 1/3 + 1/5= 1/?

I do not know. What have you done so far?

The Framers did not envision the direct election of senators by us as it is today. The Constitution had to be amended in order for that to happen. Before the early twentieth century, we elected the state legislators who in turn elected the senators. I am not quite getting what...

Algebra
Just plug in 0, -1, and 2 for x. f(x) is pretty much just another way of saying y.

math
Find a -2 along the x (horizontal) axis and draw a line. y=0 even though that is not stated. Vertical lines have a slope but you just cannot define it. Some textbooks call this no slope, but that is just a bad way of putting it.

math
By what can you multiply that would cause one of the variable letters to drop out? Positive 10 of whatever plus negative 10 of whatever else would do the job. Your first inclination was pretty much right on the money. Make sure to multiply whatever you use all the way across.

math
That can be reduced/simplified much more.

He was the first president to be born in a log cabin, by the way.

Eurasia is just something used by people who think that Europe and Asia should be considered one continent/land mass. What time period? The prologue (not capitalized) of what?

Cite with a c and not site with an s. Do you know what primary means in this context as opposed to secondary? Not everything on the web ending in dot edu or whatever else is a primary. Primary means written firsthand by someone living in the time period. These observations ...

pre algebra
The absolute value of any integer is simply its distance from zero on the number line and distance has to be positive. It is noted by two single vertical lines on the left and right hand sides of the number.

T.H. Lawrence (of Arabia). Peter O'Toole depicted in him on the silver screen. Circa the First World War.
