Answer:
The answer to your question is Ruth needs 3/2 or 1 1/2 more quarts.
Step-by-step explanation:
Data
Oil needed = 5 1/4
Oil in bottle 1 = 2 1/2
Oil in bottle 2 = 1 1/4
Process
1.- Subtract the oil in bottle 1 and bottle 2 to the amount of oil needed.
5 1/4 - 2 1/2 - 1 1/4
-Convert the mixed fractions to improper fractions
5 1/4 = (20 + 1) / 4 = 21/4
2 1/2 = (4 + 1)/2 = 5/2
1 1/4 = (4 + 1)/4 = 5/4
-Substitute
21/4 - 5/2 - 5/4
-Look for the Greatest common factor
4 2 4 2
2 1 2 2
1 1
GCF = 2 x 2 = 4
21/4 - 5/2 - 5/4 = (21 - 10 - 5)/4
= (21 - 15)/4
= 6/4
= 3/2 or 1 1/2
-Conclusion
Ruth needs 3/2 or 1 1/2 more quarts.
<u>Answer:</u> 8+(1.4x)
<u>Reasoning:</u>
The park has a $8 charge for entry, following it is $1.40 per ride so $8 would be added and the $1.40 would be multiplied by the number of rides he rode, since we don't know it will be x.
Step-by-step explanation:
= (8n² - 3n + 10) + (-3n² - 6n - 7)
= (8 - 3)n² + (-3 - 6)n + (10 - 7)
= 5n² - 9n + 3
Option → #1
(4x25)=100+(4x4)=116 That should be correct :)
