-9 would be the answer. you would round -9 1/6 to -9. 2 1/3 to 2. -1 7/8 to -2.
360 degrees = 1 full rotation
7000/360 = 19.4444... turns
perimeter or circle = 2

r
diameter = 30m
radius =15m
2

(15) = 94.24777961 per turn
94.24777961 x 19.444... turns = 1832.595714 meters traveled
Rounded = 1832.60 meters
3/4=2/4=5/4
5 divided by 4 or 5/4= 1 1/4
6 1/4+5=6 1/4
hope that helps. It wasn't very clear. so those are the questions I got out of that and those are the answers. Again hope this helps
So you have to solve for "donation" - so let's call that X. And the things we know are what the grandfather donated, as a function - meaning based upon - Theo's donation. We'll call that Y.
So Y is equal to 1/2 of $4 plus Theo's donation...... 0.5*(x+4).
So... 4.25 = 0.5(X+4), solving for X
4.25=0.5x + 2
-2 -2
2.25=0.5x - divide each side by 0.5 to get x alone.
x = 4.50
Plugging back in:
(4.50 + 4.00)*0.5 = 4.25!
Answer:

Step-by-step explanation:
We have the system

To solve the system we equate the two equations and find the value of x. Then we replace the value found in the first equation.

Then the solution of the system is the point
which does not correspond to any of the options given.
