Answer:
m = 5/4N -7
Step-by-step explanation:
Solve this the same way you would if N were a number.
N = 4/5(m +7) . . . . . . given
5/4N = m +7 . . . . . . . multiply both sides by 5/4
5/4N -7 = m . . . . . . . . subtract 7
The equation for m can be written as ...
m = 5/4N -7
Answer:
Explanation:
The problem is: <em>given the points (19,−2) and (−11,10) find the slope of the line that joins them.</em>
The <em>slope </em>of a line is the change in the y-coordinate over the change of the x-coordinate:
- slope = rise / run = Δy / Δx
Thus:
![slope=[10-(-2)]/[-11-19]\\\\slope=12/(-30)\\\\slope=-12/30](https://tex.z-dn.net/?f=slope%3D%5B10-%28-2%29%5D%2F%5B-11-19%5D%5C%5C%5C%5Cslope%3D12%2F%28-30%29%5C%5C%5C%5Cslope%3D-12%2F30)
Simplify, dividing both numerator and denominator by 6:
The question says they will run less than 36 miles, so this means they will run up to 35 miles.
They have run 22 so far, so t will be less than or equal to 35 - 22
T is less than or equal to 13.
The three angles make a total of 180
(2x+7) +(3x+2)+41=180
5x+50=180
5x=130
x=26
so angle B is 2*26+7=59 degree
