Which of the following shows one way to simplify 43Σn=1(3+9n)?
kramer

Based on the given summation notation, the expression that shows one way to simplify 43 Σ n=1 (3+9n) is (a) 43 Σ n=1 3 + 43 Σ n=1 9n

<h3>How to determine the summation expression?</h3>

The expression is given as:

43Σn=1(3+9n)

As a general rule, if a summation notation is represented using the following expression

Σ(a + bn)

The equivalent expression of the above summation notation is

Σa + bn

Where the variable a is a constant in the expression

This means that:

Σ(a + bn) = Σa + bn

Using the above equation as a guide, we have the following equivalent equation

43 Σ n=1 (3+9n) = 43 Σ n=1 3 + 43 Σ n=1 9n

Hence, based on the given summation notation; the expression that shows one way to simplify 43 Σ n=1 (3+9n) is (a) 43 Σ n=1 3 + 43 Σ n=1 9n

Lanie is saving money to buy a car. She saved $772 so far. She earns $157 every month. How many months until Lanie has saved $2,
ser-zykov [4K]

Answer:

<u>9</u> months until Lanie has saved $2,176.

Step-by-step explanation:

Given:

Lanie is saving money to buy a car. She saved $772 so far.

She earns $157 every month.

Now, to find the months until Lanie has saved until $2,176.

Let the number of months Lanie has saved be x.

She earns per month = $157.

She saved so far = $772.

<em><u>According to question:</u></em>

So, to get the months lanie has saved until $2,176 we write an equation.

157x+772=2176

<em>Subtracting both sides by 772 we get:</em>

157x=1404

<em>Dividing both sides by 157 we get:</em>

x=8.95<em />

<u><em>So, the number of months nearest to the month = 9.</em></u>

Therefore, 9 months until Lanie has saved $2,176.
