2x - 2y = 14 \\ x = 2 + y \\  \\ 2(2 + y) - 2y = 14 \\ 4 + 2y - 2y = 14 \\ 4 = 14
Since 4 does not equal 14, this answer is no solution.

The volume (in cubic meters), v, of a rectangular room is given by the expression:
yan [13]

Answer:

  7(b^2 -2)(b^2 +2)

Step-by-step explanation:

Factoring the common factor 7 from both terms, you get the difference of squares. That can also be factored.

  v = 7(b^4 -4) = 7(b^2 -2)(b^2 +2)

The difference b^2-2 will have irrational factors, so does not meet the problem requirements. This is the factorization over integers.

In order to make a profit, a retailer sells dresses at 130% of the price she paid for them. A dress in the shop priced at $78.95
Stels [109]

Answer:

$102.635

Step-by-step explanation:

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 78.95 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 78.95 is 100%, we can write it down as 78.95=100%.

4. We know, that x is 130% of the output value, so we can write it down as x=130%.

5. Now we have two simple equations:

1) 78.95=100%

2) x=130%

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

78.95/x=100%/130%

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 130% of 78.95
