The answer is no solution

Step-by-step explanation:

The equation is -2x+y=6 and -2x+y=-1

Subtracting these two equations, we get,

-2x+y=6\\-2x+y=-1\\-------\\0=7

Thus, 0=7 is not possible.

Hence, the system of equations have no solutions.

A newspaper advertisement offers a $6500 used car for nothing down and 36 easy monthly payments of
NNADVOKAT [17]

Using simple interest, it is found that:

  • The total amount paid was of $7,084.8.
  • The finance charge was of $584.8.
  • The simple interest rate was of 3%.

<h3>Simple Interest</h3>

Simple interest is used when there is a single compounding per time period.

The amount of interest after t years in is modeled by:

I = Prt

In which:

  • P is the initial amount.
  • r is the interest rate, as a decimal.

In this problem, the amount paid was of 36 monthly payments of

$196.80, hence:

36 x 196.80 = $7084.8.

The total amount paid was of $7,084.8.

The original price is of $6,500, hence the finance charge was of:

7084.8 - 6500 = $584.8.

For interest, we have that:

I = 584.8, P = 6500, t = 3, hence:

I = Prt

584.8 = 6500(3)r

r = \frac{584.8}{6500 \times 3}

r = 0.03

The simple interest rate was of 3%.

Mr. Evan is paid $9.20 per hour for the first 40 hours he works in a week he is paid 1.5 times that rate for each hour after tha
faust18 [17]
That is incorrect. The correct answer should be $398.38
First you take 9.2 times 40 and you get $368 which is how much he got paid for the first 40 hours. now he worked 2.25 hours extra so you take 9.2 * 1.5 because he gets 1.5 times more for extra hours. Then you add that to the $368 and you get $398.38
