Answer: 14 gallons
Step-by-step explanation:
Let's call the total gallons of gas Abdul's tank can hold <em>x</em>.
Then, based on the information given in the problem, you can write the following expression:

Therefore, when you solve for x, you obtain the following result:

5 and 1/4 times 3. 1/4 is equal to .25. So, 5.25 x 3 is...
15.75
-17/15
Find a common denominator, and multiply the numerator by the same factor. Don't forget that adding a negative is really subtracting.
AB ≈ ED ( corresponding sides )
∠A ≈ ∠D ( corresponding angles )
∠C ≈ ∠F ( corresponding angles )
You use the formula a² +b² =c²
so 4² +b² =8²
solve for b
