Answer:
number o students bought pennants = 18
number of student bought fancy ones=12
Step-by-step explanation:
Let x be the number o students bought pennants
and y be the number of student bought fancy ones
total 30 students


Plain pennants cost $4 each and fancy ones cost $8 each.

Substitute 30-x for y in second equation



Subtract 240 from both sides

divide both sides by -4
x=18


number o students bought pennants = 18
number of student bought fancy ones=12

Answer:
P(5) = 26
P(-5) = 6
Step-by-step explanation:
The remainder statement tells us ...
P(x) = Q(x)·(x +5) +6
Evaluating this for x=5, we get ...
P(5) = Q(5)(5+5) +6
P(5) = (2)(10) +6
P(5) = 26
And for x = -5, we have ...
P(-5) = Q(-5)(-5 +5) +6
P(-5) = 0 +6
P(-5) = 6
If the angle is 1/12 of the circle, and a circle is 360 degrees, then our answer will be 1/12 of 360.
1/12 * 360 = 30 degrees
The answer is 30 degrees.
