What is 9m-28=2m explain

Answers

Subtract 2m on both sides, which leaves you with 7m=-28, divde -28 with 7 and equals to -4
-4=M

9m-28=2m
9m-28-2m=2m-2m
(9m-2m)-28=0
7m-28=0
7m-28+28=0+28
7m=28
(7m)/7 = 28/7
m=4

A bank offers a CD that pays a simple interest rate of 6%. How much must you put in this CD now in order to have $11 comma 700 to replace all the windows in your house in 5 years?

Answers

Answer:

You should invest US$ 9,000 in the CD to replace all the windows in your house.

Step-by-step explanation:

Let's recall that the simple interest formula is:

A = P * (1 + r * t), where,

A = final amount

P = initial principal balance

r = annual interest rate

t = time (in years)

Replacing with the real value, we have:

11,700 = P * (1 + 0.06 * 5)

11,700 = P * (1.3)

P = 11,700/1.3

P = 9,000

You should invest US$ 9,000 in the CD to replace all the windows in your house in 5 years.

Final answer:

To calculate the initial deposit for a CD with a 6% simple interest rate in order to have $11,700 in 5 years, you can use the simple interest formula. The formula is rearranged to solve for the initial deposit amount: P = I / RT, where 'P' is the initial deposit, 'I' is the desired amount, 'R' is the interest rate, 'T' is the CD term.

Explanation:

The subject of the question is about how much initial deposit you must put into a CD with a simple interest rate of 6% in order to have $11,700 in 5 years. You can find this out by using the formula for simple interest, which is I = PRT. 'I' is the interest, 'P' is the principal amount (what you want to find out), 'R' is the rate of interest, and 'T' is the time in years.

Since you want to find out 'P' (the principal amount), you'd rearrange the formula to P = I / RT. Now you substitute 'I' with $11,700, 'R' with 0.06 (6% expressed as a decimal), and 'T' with 5 years. So, P = $11,700 / (0.06 * 5). From this calculation, you'll be able to determine how much money you need to deposit now into your CD to reach your goal.
