Erwin began the month with a bank balance of $0. His bank statement shows one credit (+) and one debit (-). HIs balance at the end of the month was $15. What could be the amounts shown as Erwin's bank statement. Explain how you got your answer.

Answers

Answer:

Credit ⇒ 45

Debit ⇒ $30

Step-by-step explanation:

Credit = $45

Debit = $30

When an account balance increases it means that it has been credited and when it decreases, it has been debited.

The beginning balance here is $0 and the closing balance is $15.

There were 2 transactions, one credit and one debit.

For the closing balance to be $15, the Credit amount must have been $15 more than the Debit amount.

Answers

Answer:

Prancer spent 240$

Dasher spent 120$

Cupid spent 360$

Step-by-step explanation:

Dasher = D

Prancer = P

Cupid = C

"Dasher spent half as much as Prancer"

D = 1/2P

"Cupid spent 3 times more than Dasher"

C = 3 * D

C = 3 * 1/2P

P + c + d = 720

P + 1/2p + 3*1/2P = 720

3P = 720

3P/3 = 720/3

P = 720/3

P = 240

Prancer spent 240$

Dasher spent 120$ (240/2)

Cupid spent 360$ (120*3)

Answer:

Dasher spent $120, Prancer spent $240, and Cupid spent $360

A 324 -inch pipe is cut into two pieces. One piece is five times the length of the other. Find the length of the shorter piece.

Answers

Answer:

64.8 in

Step-by-step explanation:

The pipe is 324 in and you cut in in two. Since we know that one piece is five times the length of the other, we can make the equation 324=5x. Divide both sides by five gets us 64.8 = x.

To check our work, let's multiply 64.8 by 5. It does equal 324 so we are correct.

Step-by-step explanation:

i added it to a graph.

Answer: You can use the distance formula to find the distance between any two points ion the plane. In this case, look carefully at the coordinates:

R(-1, 7) and T(-7, 7), Notice they both have y-coordinate 7. That means they are both on the same horizontal line. To find their distance, just subtract -7 from -1 and take the absolute value.

|-1 - (-7)| = |-1 + 7| = |6| = 6

The distance is 6 units

What is a reciprocal?

The definition of reciprocal in mathematics is the inverse of a value or a number. If n is a real number, then 1/n will be n's reciprocal.

Given:

The number is 7.

Let n be the reciprocal of 7.

If n is a real number, then 1/n will be n's reciprocal.

To find the reciprocal of 7:

We need the value that can give us 1 when multiplied by 7.

That means,

n x 7 = 1

Divide by 7 to both sides,

n = 1/7

Therefore, the reciprocal is 1/7.
