Kay [80]

Step-by-step explanation: Answer: around 64 minutes

We need to first set the two equal to each other.

We can model the first part using the slope intercept form.

y=.17x+15

We are trying to find the amount of minutes or x she can spend. We solve for x by using inverse operations.

However, the question states that she has already paid the flat fee of 15 dollars, so we are only doing .17x=10.92 (inverse operations for x)

X=64.23 minutes or around that.

Abdul's gas tank is 1/5 full. After he buys 7 gallons of gas, it is 7/10 full. How many gallons can Abdul's tank hold?
eduard

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:

\frac{1}{5}x+7=\frac{7}{10}x

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

\frac{1}{5}x+7=\frac{7}{10}x\\\\\frac{1}{5}x-\frac{7}{10}x=-7\\\\-\frac{1}{2}x=-7\\\\-x=(-7)(2)\\x=14
