Answer:
6n + 9
Step-by-step explanation:
6 times a number can be written as "6n"
9 more than 6n can be written as 6n + 9
1) Add 10 on both sides
-6+10= (n/2)-10+10
4= n/2
2) multiplying 2 on both sides
4(2)= (n/2)(2)
8=n
Thus the answer is 8 for n.
Hope this helps!
Answer:
66 degrees
because Angle EAG is a corresponding angle and its measure is 81 which means that Angle HAJ is also 81. So the last step is the actual angle which is 81 minus 15 which equals 66 degrees
all students = 150
M = 60
S = 45
M and S = 25
(a) At least one of the two requirements:
M or S = M + S - (M and S) = 60 + 45 - 25 = 80
(b) Exactly one of the two requirements:
(M or S) - (M and S) = 80 - 25 = 55
(c) Neither requirement:
(all students) - (M or S) = 150 - 80 = 70
