Answer: Pythagorean theorem.
a^2+b^2=c^2
6^2+7^2=c^2
36 + 49 = c^2
85 = c^2
sqrt of 85 = 9.22

50km=50000m

So 1hour can travel 50000m

This one just scares me how do i even figure this out?

Because the middle point is in the center of the square, the triangle containing angle 2 is isosceles and right (since two sides are equal to half the square's side length), so angle 2 measures (180-90)/2=45 degrees.

Y − x = -13 -4x + 3y = -51

Answers

y - x = -13
-4x + 3y = -51

Use any of the equation to find the value of x or y. In this case, I'll use the 1st equation to find the value of y.

y - x = -13
y = x - 13

Substitute the value of y in the 2nd equation to find the value of x.

-14x + 3y = -51
-14x + 3(x-13) = -51
-14x + 3x - 39 = -51
-11x = -51 + 39
-11x = -12
x = 12/11 or 1 1/11

Substitute the value of x in any equation to find the value of y.

y = x - 13
y = 12/11 - 13
y = 12/11 - (13*11/11) *to get the common denominator
y = (12 - 143)/11 = -131/11 = 11 10/11 

to check: x = 12/11 or 1 1/11 ; y = -131/11 or 11 10/11

y - x = -13
-131/11 - 12/11 = -13
(-131 - 12)/11 = -13
-143/11 = -13
-13 = -13
