James wants to buy some CDs that cost $14 each and a DVD that costs $23. He has $65. Write an equation (in the Show your work area) and solve to find how many CDs he can buy. Include "CD" in your answer.

Answers

Answer:

3

Step-by-step explanation:

65-23= 42

42/14= 3

Answer:

14x+23 =65 x=3CDs

Step-by-step explanation:

So for any question where you need to write your own equation, it is first necessary that you determine what each number in the problem means in order to determine where they should go. James has $65 so the equation needs to be set equal to 65. The problem says he wants to buy a DVD for $23 so that would be a constant $23 spent regardsless of how many CDs he buys. We are trying to use the equation to determine how many CDs James can buy so the number of CDs is the x value at $14 each which would be 14x in the equation. so the equation would be the 14x for the unknown number of CDs, plus 23 for the constant DVD that James would buy set equal to the $65 he can use to buy everything.

To solve the equation, you must now isolate for x. To start, cancel out the +23 on the left side by subtracting 23 from both sides. This will leave 14x=42. You must then cancel the 14 by dividing both sides by 14 leaving your answer of x=3CDs.

I hope this helps.

Janiya hiked 4/5 of a mile in 1/3 of an hour what is the hiking speed in miles per hour

Answers

The answer is 12/5 or simplified to 2 2/5

Answer:

Janiya has a speed of [tex]2\frac{2}{5}[/tex] miles per hour.

Step-by-step explanation:

Given that:

Distance covered = 4/5 of a mile

Time taken to cover the distance = 1/3 of an hour

Speed is defined as the distance travelled in a certain time.

Speed of Janiya = [tex]\frac{Distance}{Time}[/tex]

Speed of Janiya = [tex]\frac{\frac{4}{5}}{\frac{1}{3}}[/tex]

Speed of Janiya = [tex]\frac{4*3}{5*1}[/tex]

Speed of Janiya = [tex]\frac{12}{5}[/tex]

Speed of Janiya = [tex]2\frac{2}{5}[/tex] miles per hour

Hence,

Janiya has a speed of [tex]2\frac{2}{5}[/tex] miles per hour.

Every year Chana uses her income from her job to pay for 80% of her college tuition. Next year Chana will need to contribute $2,000 toward her tuition. Next year the tuition will be $600 more than this year's tuition. How much is this year's tuition?

Answers

Answer:

$1400

Step-by-step explanation:

Given that:

80% of the college tuition was paid from the income of Chana.

Next year, Amount to be contributed toward the tuition = $2000

Next year, the tuition will be $600 more than this year's tuition.

To find:

Amount of this year's tuition = ?

Solution:

Let the amount of this year's tuition = $[tex]x[/tex]

As per the question statement, next year's tuition will be $2000 which is $600 more than this year's tuition fee.

Writing the equation:

[tex]x+\$600 = \$2000\\\Rightarrow \bold{x = \$1400}[/tex]

This year's tuition fee is $1400.
