The sum of two consecutive positive even integers is at most 14. List all possible pairs of integers.
anastassius [24]
Let X be the first number
there is a 2 numbers distance between each even number eg.2 ,4, 6, 8, etc.
So the 2nd number is X+2
The sum of the 1st and 2nd numbers = 14
X + X+2 =14
2X +2 =14
2X = 14-2
2X = 12
X = 12/2
X = 6
Therefore,
The first number i.e, X = 6
And the second number i.e, X+2 = 6+2 =8
******************************************************************************
This is the only positive pair in case of two consecutive numbers if the are even numbers but not consecutive there will be more pairs
12 + 2 = 14
10 + 4 = 14
8 + 6 = 14 (Already found)

On a trip, Alexander bought a ping-pong racket for $13. With the tax, he paid $14.04. What is the tax rate, in percent?
Fed [463]

Answer:

8% tax rate.

Step-by-step explanation:

\frac{14.04}{13} =1.08

The 8% (0.08) is the tax rate because the 100%, or 1.00, is the original price of the racket, which was $13.

-104=-8(k+8) <br><br> K = ?<br> Solution please if can?
maksim [4K]

Let's solve this question by step by step.

Layout equation.

−104=−8(k+8)

Step 1: Simplify both sides of the equation.

−104=−8(k+8)

−104=(−8)(k)+(−8)(8)(Distribute)

−104=−8k+−64

−104=−8k−64

Step 2: Flip the equation.

−8k−64=−104

Step 3: Add 64 to both sides.

−8k−64+64=−104+64

−8k=−40

Step 4: Divide both sides by -8.

-8k/-8=-40/-8

The answer for this problem is k=5.

A school survey reported that
kozerog [31]

The probability that the student has  a part-time job, given that they  have a cell phone is 5/8

<h3>What is probability</h3>

Probability is the likelihood or chance that an event will occur.

Given the following parameter:

  • Total student = 80%
  • Part-time jobs = 45%
  • Those with both a cell phone  and a part-time job = 30%

Student will cellphone only = 80 - 30 = 50%

The probability that the student has  a part-time job, given that they  have a cell phone is 50/80 = 5/8

Joyce saved $70 on an item that was 75 % % off. What was the original price?
SashulF [63]

if Joyce saved $70

at 75% off, Joyce saved 25%

so, $70 is 25%

To find the total price which is 100%, multiply $70 by 4 ( because 25% x 4 = 100% )

so the original price is $70 x 4 = $280
