You need 5 more gallons for a full tank.
Since it takes 10 gallons to increase the gauge from 1/4 to 3/4 (change of 2/4 which is the same as 1/2), it must have taken 10 gallons to fill up to halfway for the tank.
Thus the full amount would be 10*2 = 20 gallons
However, since there is already 3/4 gasoline in the tank, we only need an extra 1/4 of 20 for it to be full.
So, 20*1/4 = 5
We need to add 5 gallons for a full tank.
Answer:
Step-by-step explanation:
Any negative exponent can be moved to the other side of the fraction as a positive exponent.
Thus, simply move the negative exponents from the bottom into the numerator to get. -10a^2*b^4*5a^9*b^5. Then, use the exponent rule to get
