Answer:
9
Step-by-step explanation:
Whatever you do to the denominator, you've got to do to the numerator, and vice versa. So for 8 to become 24, you multiply by 3. do that to the numerator 3 as well. 3 × 3 is 9.
The resulting equation that Kent has when he moves all the terms to one side of the equal sign is k² - 8k + 12 = 0
<h3>What is quadratic equation?</h3>
A quadratic function is a function that usually has a single variable and it is raised to the power of 2. An example is x² + 10x + 25 = 0
Given this equation: k + 12/k = 8
If both sides are multiplied by k, the equation becomes: k² + 12 = 8k
If all the terms are moved to one side of the equal sign: k² - 8k + 12 = 0

Answer:
A
Step-by-step explanation:
Given that y varies inversely with x then the equation relating them is
y = 
To find k use the condition y = 48 when x =
, thus
k = yx = 48 ×
= 16
y =
← equation of variation
The answer is shown in the paper above
Answer:
A + C
Step-by-step explanation:
n = how much the guitar costs.
You know that you spent $45 on the lesson, and the cost of the lesson plus the cost of the guitar equals 325.
280 comes from 325, the cost of the guitar and the lesson, plus the cost of the lesson.
hope this helped! :)
