X = 30 because the ratio of 27/45 = .6 so 18/.6 is 30
The answer are (1, 5) and (1, 3)
If I'm understanding this correctly then 3 is your answer, but to be sure you'd have to be specific on how many papers and ribbons are in each pack.
<h3>
Answer: approximately 5.1724%</h3>
Work Shown:
2 hrs, 45 min = 120 min + 45 min = 165 min
2 hrs, 54 min = 120 min + 54 min = 174 min
A = estimated value = 165
B = true value = 174
C = percent error
C = 100*( |A - B| )/B
C = 100*( |165-174| )/174
C = 100*( | -9 | )/174
C = 100*9/174
C = 900/174
C = 5.1724% which is approximate
3/4 C
-1.5 A
3^2 G
0.5^3 B
30 E
