Answer:
x = 28
Step-by-step explanation:
Let the total number of students = x
x/7 + 3x/7 + 2x/7 + 4 = x If that is all there is. If it isn't the problem can't be done. Combine like terms.
x(1 + 3 + 2)/7 + 4 = x
x (6/7) + 4 = x Subtract 6x/7 from both sides
4 = x - 6x/7
4 = 7x/7 - 6x/7 Combine
4 = 1/7x Multiply both sides by 7
4*7 = 7x / 7
x = 28
Hey where is the graph for Function B?
Using the interest formulas, it is found that the values of the investment are given as follows:
- Using simple interest, the value will be of $34,000.
- Using compound interest, the value will be of $144,461.
- Using continuous compounding, the value will be of $148,002.
<h3>Simple Interest</h3>
Simple interest is used when there is a single compounding per time period.
The amount of money after t years in is modeled by:

In which:
- r is the interest rate, as a decimal.
In this problem, we have that the parameters are as follows:
P = 9000, r = 0.07, t = 40.
Hence:

<h3>Compound interest</h3>

n is the number of compounding, for quarterly n = 4, then:


<h3>Continuous compounding</h3>

Hence:

Answer:
52+p
Step-by-step explanation:
The expression says "add p to 52", so we know that we need to sum two values, one of them is the variable 'p', and the other is the value 52.
So, writing this expression in mathematical terms, we have:
52+p
With this expression, we added p to the number 52.
So the correct answer is the last one (the fifth one)
