Step-by-step explanation:
Order of congruence does not matter. For any angles A,B, and C , if ∠A≅∠B and ∠B≅∠C , then ∠A≅∠C . If two angles are both congruent to a third angle, then the first two angles are also congruent.
Turn 4 1/2 into a fraction which is 4.5, then divide that by three. 4.5 / 3 = 1.5. So 1.5 = 1/3 of the original amount. Now all you need to do is multiply 1.5 times 2. You do this because you know that 1/3 + 1/3 = 2/3. So 1.5 + 1.5 = 2/3. 1.5 * 2 = 3. Now you have 2/3 of the original number.
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.
In this case the variable x is an EXPONENT and the function should be written:
y = 3ˣ + 1
It’s C, I got this because if you add it all together you get c.
