Answer: yards = 7.5. FeeT =21.75 inches=261
Step-by-step explanation:
<em>x = 36</em>
- Step-by-step explanation:
<em>2x + 27 = 3x - 9</em>
<em>27 + 9 = 3x - 2x</em>
<em>x = 36</em>
$481, let me know if you want the solution with the work.
Find the slope of the first line, that is the difference of the y’s over the difference of the x’s. This way: 2-5/2-5=-3/-3 which equals 1
Now find the slope of the second line 2-(-6)/-5-3
=8/-8
=-1
The slopes are opposite reciprocal ( you could also say that the product of the 2 slopes equals -1) therefore the lines are perpendicular.
