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

eduard

Answer:

<h2>x = -9 and x = -10</h2>

Step-by-step explanation:

f(x)=\dfrac{x^2+11x+18}{x^2+19x+90}\\\\\text{DOMAIN:}\\\\x^2+19x+90\neq0\\\\x^2+9x+10x+90\neq0\\\\x(x+9)+10(x+9)\neq0\\\\(x+9)(x+10)\neq0\iff x+9\neq0\ \wedge\ x+10\neq0\\\\x\neq-9\ \wedge\ x\neq-10

\\\\\text{Therefore the vertical asymptotes are:}\\\\x=-9\ and\ x=-10.
