We are asked to find f(x) and g(x) so the function can be expressed as y = f(g(x) such that y = y =2/x^(2) + 3. There are many possibilities here but we go to the simplest ones. we can have g (x) = x2 and f(x) is equal to 2/x + 3.
Let's write the total of gallons in improper fraction:
Step 1: Multiply the denominator by the whole number
6 × 5 = 30
Step 2: Add the answer from Step 1 to the numerator
30 + 1 = 31
Step 3: Write answer from Step 2 over the denominator
5 1/6 = 31 / 6
Let's divide the total gallons by what she used each hour to get the number of hours:

Let convert the improper fraction to mixed number:
93/10 = 9 3/10
<h2>She was driven a total of 9 3/10 hours</h2>
The lcm of 120 and 20 is 120!
20 = 2 x 2 x 5
120 = 2 x 2 x 2 x 3 x 5
LCM = 2 x 2 x 2 x 3 x 5
Answer: 500 dollars
You just plug in 100 to the x’s in the equation
