Answer:
5.325 gallons or 
Step-by-step explanation:
According to the given problem, Dr. Silva's tank holds up to 16 7/8 gallons = 16.875.
Transform 7/8 into decimal: Divide the numerator by the denominator = 0.875. Add that to 16, and you'll have the full tank capacity of 16.875.
Next, the prompt states that she filled 11.55 gallons' worth of gas. To find how much her tank had before she filled it, you could simply subtract the full tank capacity and the amount of gass added into the tank.
16.875 - 11.55 = 5.325 gallons or (13/40 is the same as 0.325).

<span>Step 1 :</span><span>Step 2 :</span>Pulling out like terms :
<span> 2.1 </span> Pull out like factors :
<span> t2 - 8t</span> = t • (t - 8)
<span>Equation at the end of step 2 :</span> t • (t - 8) = 0

<span> 3.1 </span> A product of several terms equals zero.<span>
</span>When a product of two or more terms equals zero, then at least one of the terms must be zero.<span>
</span>We shall now solve each term = 0 separately<span>
</span>In other words, we are going to solve as many equations as there are terms in the product<span>
</span>Any solution of term = 0 solves product = 0 as well.
Solving a Single Variable Equation :

</span> Solution is t = 0
Solving a Single Variable Equation :
<span> 3.3 </span> Solve : t-8 = 0<span>
</span>Add 8 to both sides of the equation :<span>
</span> t = 8

Answer:
Gary can go 4.9 miles in 84 minutes.
Step-by-step explanation:
First, you need to determine the amount of hours 84 minutes represent considering that 60 minutes are equal to an hour:
60 minutes → 1 hour
84 minutes → x
x=(84*1)/60=1.4 hours
Now, 1.4 hours would be the time which is x and you can replace the value on the formula to find y:
y=3.5x
y=3.5(1.4)
y=4.9
According to this, the answer is that Gary can go 4.9 miles in 84 minutes.
