sorry it took a long time
Supplementary = 180 so 3x+5+7x+6=180 10x+11=180 10x=169 x=16.9 3(16.9)+5 50.7+5 55.7 so 55.7 degrees
Step-by-step explanation:
y=mx+c
-4=6(12)+c
-4=72+c
-4-72=c
c=-76
y=mx+c
y=6x-76

Let's find out the gradient (Slope " m ") of line q ;



Now, since we already know the gradient let's find of the equation of line by using its Slope and one of the points using point slope form of line :


Now, plug in the value of gradient ~

here we can clearly observe that, the Area under the curve can easily be represented as :

Since, all the values of y that lies in the shaded region is smaller than the actual value of y for the corresponding values of x in the equation of line q
8159 divided by five times two then, divide that by twenty and multiply by 13, The answer is about 2611 kids wore helmets properly while riding bike
