The answer to this question would be:
f(x) = 7 + 0.3x
Because 2 pounds will cost you $7, the $7 is required. If x is the number of ounces over 2 points and each ounce is 30 cents, it would only seem reasonable to multiply the ounces by 30 cents, right? Right. Therefore you add the 0.3x and you come towards the correct answer.

Step-by-step explanation:
Answer: x = 3. the length of side ST is 14.
Step-by-step explanation:
Since both sides are equal, we can use the equation 3x + 5 = 5x - 1.
To start the problem, we subtract 3x from each side which makes our equation 5 = 2x - 1.
The next step would be to simplify the equation by adding 1 to each side which makes our equation 6 = 2x.
We then need to simplify the equation to x = 3.
This means the answer to 9 is x = 3.
For the next problem, since we already know the value of x, we substitute its value which in this case would be 3. This leaves us with an equation of 9 + 5, which equals 14.
This means the length of side ST is 14.
