A washer and a dryer cost $814 combined. the washer costs $36 less than the dryer. what is the cost of the dryer?

Answers

This is a systems of equation problem.
First, set up the equation.
814=w+d w=d-36

Second, insert w= in for w in the equation.
814=d-36+d

Third, combine like terms.
814=2d-36

Fourth, solve the equation by adding 36 and dividing by 2 to both sides.
814=2d-36
+36 +36
___________

The sum of two odd numbers is 198. Both of the numbers are multiples of 3. One of the numbers is 5 times the other. Which equation could you use to find the two numbers?

Answers

Answer:

The equation used to find the two numbers is:

x+5x=198

and numbers are:

33 and 165

Step-by-step explanation:

The sum of two odd numbers is 198.

One of the numbers is 5 times the other.

Let one number be x

other number=5x

⇒ x+5x=198

⇒ 6x=198

Dividing both sides by 6,we get

x=33

Other number=5x=5×33=165

The equation used to find the two numbers is:

x+5x=198

and numbers are:

33 and 165

You could use m= the lesser number and n as the greater number. Since one is 5 times the other you will start with m+5m=198. Then you will combine like terms so it will become 6m=198. Then you will solve it as a regular equation. m=33 and n=165.

To borrow money, you pawn your guitar. based on the value of the guitar, the pawnbroker loans you $840. one month later, you get the guitar back by paying the pawnbroker $1,472. what annual interest rate did you pay? round to the nearest tenth of a percent.

Answers

It would be: 1472/840 * 100 = 147200/840 = 175.02

So, it is 75.02%

For nearest 10th percent it will be 75%

SO 75% IS YOUR ANSWER

Final answer:

The student paid a 900.0% annual interest rate on the loan provided by the pawnbroker.

Explanation:

To calculate the annual interest rate you paid, you need to note that the difference between the amount you paid back and the amount you borrowed is the interest. That's $1,472 - $840 = $632. The way interest works is that you pay a certain percentage of the original amount you borrowed (the principal). So, if we express the interest as a percentage of the principal, we get $632 / $840 = 0.75, or 75%. However, this is the interest rate for one month, as you only held the loan for one month. The annual rate would be this monthly rate multiplied by the number of months in the year, which gives 75% * 12 = 900%. So, the annual interest rate you paid, to the nearest tenth of a percent, is 900.0%.
