What is an Equation

An equation is an expression that is used to show the relationship between two or more numbers and variables.

Let x represent the amount of money invested, hence:

Value of money now = x + 11% of x = x + 0.11x = 1.11x

180(n-2)=s
solve for n
please help me

Answers

Answer:

n = (s + 360)/ 180

Step-by-step explanation:

180(n - 2)= s ? ummm ill try...

180n - 360 = s

180n = s + 360

n = (s + 360)/ 180

Answer:

n = s/180 +2

Step-by-step explanation:

180 (n-2) = s

Step 1: To find n, we need to get rid of 180 from the left side of the equation. Divide 180 by both sides; then we can cross out 180 with itself on the left, leaving (n-2)

180 (n-2) /180 = s/180

Step 2: Now we got rid of 180 on the left, we must isolate n. To do that, we must bring -2 to the other side of the equation. There, it would become positive, and n gets isolated.

n = s/180 + 2

Although, you may or may not be confused with my answer, and I realized that there's two ways to solve this. Let me show you:

Step 1: 180(n-2) = s

Distribute - multiply 180 with every term in the brackets, which then we would end up with:

180n-360 = s

Step 3: Bring -360 to the right side of the equation, where it would become positive.

180n = s+360

Step 4: To isolate n, divide 180 by both sides of the equation:

180n/180 = s+360/180

Step 4: Now you have:

n = s+360/180.

Though you could leave your answer as the one above, you should simplify it.

Step 5: n = s/180 + 360/180

360/180 = 2, therefore the simplified answer is:

n = s/180 +2

Trevor is tracking the value of a stock he invested in over the course of one business day (8 hours). The value of the stock can be found be adding these two functions, where t represents time in hours:
f(t) = 12(1.20)t
g(t) = -4.5t

Answers

The function v(t) is a composite function of the stock functions f(t) and g(t)

Add the functions f(t) and g(t)

The functions are given as:

f(t) = 12(1.20)^t

g(t) = -4.5t

When both functions are added, we have:

v(t) = 12(1.20)^t - 4.5t

The graph of the function v(t)

See attachment for the graph of the function v(t)

The initial value from the graph

This is the point where t = 0

From the graph of the function, the initial value is 12

The final value from the graph

This is the point where t = 8

From the graph of the function, the final value at the end of the day is 15.598

The behavior of the stock

From the graph, we can see that the stock value decreases to a minimum and then increases.

When the stock is at the lowest

From the graph, we can see that the stock value is at t = 3.955

This means that the stock is at the lowest after about 4 hours

Answers

Answer: 35%

Step-by-step explanation:

- To start off divide 100% by the 20$ it began with, it should give you 5%

100/20 = 5

this means that every dollar is worth 5%

- now leaving that aside, subtract 20$ by 13$, it should give you 7$

2--13 = 7

the reason you do this is because since we're looking for the amount reducted, you have to subtract from the beginning amount.

- Finally, with the knowledge gathered, you multiply 5% by the 7$ that were deducted, it should give you 35%

7(5) = 35

The reason we did this is because every dollar is worth 5% and there were 7$ deducted, it results in 35% reduced.

Answer: 35%

Step-by-step explanation: I turned 13 and 20 into 13/20, or 13 out of 20 dollars charged. Then, I multiplied 13/20 by 5/5, which equals 65/100, or 65% or the original price was paid. The other 35% of the 20 dollars wasn’t, because that’s how much of the original price was discounted.
