(3 hours) / (8 friends) = <em>3/8</em> hour per friend
I believe it’s y=4x+4 :)
The slop intercepts the y axis at positive 4, which gives us the y intercept
If you use the rise over run technique to find the slope you’ll get 4/1, meaning the slope is 4
Arc PR is 156 degrees. Since both angles are are making the forming arc they should be congruent. You can put (5x+23)=(9x-21) which is x=11.
Then you plug in 11 into your equation; 5(11)+23=78.
Since the vertex is on the outside of the circle then the arc is forms is 2 times the value of the angle.
78(2)=156
The easiest way to to this it to make 75% a decimal. To do that you have to divide by 100 making it .75. After you have .75 just multiply it to 18 and you get...13.5
