TIME REMAINING

Answer:

$1,131.20 is the amount earned

Step-by-step explanation:

Key skills needed: Simple Interest Formula, Operations ( +, - , x , / )

1) To understand this problem, you need to know the simple interest formula.

A = P(1+rt)

A is the amount

P is the principal

R is the interest rate as a decimal

T is the time in years

2) The 1st thing we need to do is convert the interest rate into a decimal. We have 14%. To convert into decimal form, we divide it by a 100, or move the decimal 2 places to the left. This is 0.14 --> So r=0.14

3) Next we use the formula:

A = 1,010(1+ 0.14(8))

We first do 0.14(8) which is 1.12 and then add it to the 1 value, so you will get --> A = 1,010(2.12)
Multiply and you will get A = $2,141.20
To find the interest earned, you subtract this by the original amount, so $2,141.20 - $1,010 which would be $1,131.20

This means $1,131.20 is your answer.

Hope you understood and have a nice day!! :D

In order to slove the following system of equations by addition, which of the following could you do before adding the equations

Vladimir [108]

Answer:

B. use multipliers -3 and 2

Step-by-step explanation:

If you're solving the system by "addition," multiplying the equations by the chosen numbers needs to result in opposite coefficients for one of the variables.

<h3>Effect of answer choices</h3>

A. The system becomes ...

12x -6y = 21
12x -12y = 60

No variable has opposite coefficients.

__

B. The system becomes ...

-12x +6y = -21
6x -6y = 30

The y-variable has opposite coefficients. This is a good choice.

__

C. The system becomes ...

12x -6y = 21
6x -6y = 30

No variable has opposite coefficients.

__

D. The system becomes ...

4/3x -2/3y = 7/3
3x -3y = 15

No variable has opposite coefficients.

__

Additional comment

The simplest "no brainer" solution is to use the coefficients of one of the variables, negating one of them. Multiply each equation by the opposite equation's coefficient. Here, the y-coefficients are -2 and -3, and the multipliers of answer choice B are -3 and 2, consistent with this advice. (The sign of 2 was changed.)
