so the greatest common factor (GCF) of 81 and 18 : 9
Answer is C. 9
Shape A is congruent to Shape B because If you were to rotate one of the two and flip it the would like up and match.
Answer:
30 out of 50 times.
Step-by-step explanation:
1 attempt represents 3 out of 5 times.
10 attempts equals 1 attempt x 10.
Multiply numbers 3 and 5 by 10.
3 x 10 = 30
5 x 10 = 50.
Therefore, your solution is 30 / 50 times.
180-55-39=86
x=86

It would be 1n - 12 + 8y.
4n - 3n = 1n
12 + 8y don’t mix so we can leave it.
Therefore: 1n - 12 + 8y
