Answer:
c. 18
Step-by-step explanation:
First, you would find the total sum of the 60 numbers. The average is always the sum of the numbers divided by the number of numbers.
35*18=630
15*10=150
Now we do not know how many numbers the last group has. However, we can find it out doing 60-35-15 to see how many numbers are left. There would be 10 numbers left
10*30=300
630+150+300=1080
1080/60=18
Hence, the answer is C(18)
Answer:
z = 106, y = 23
Step-by-step explanation:
z and 74 is a supplementary angle which is equal to 180 degrees.
z + 74 = 180
z = 106
5y - 9 and z is a vertical angle, so the are equal to
each other.
5y - 9 = z
5y - 9 = 106
5y = 115
y = 23
