A digital camera for $249.99 at 4% sales tax

Answers

First, change the 4% into a decimal. Once thats changed, it will be 1.04
Multiply 1.04 by the amount of the cost, to get your answer.
But, to make this easier, and to not go through more work, lets round your money amount to $250
Now, all you have to do is multiply.
$250 · 1.04 ≈ $260
So, your answer for $250 with 4% (1.04) percent sales tax would be a grand total of:
$260

-Hope this helped :)
i'll round the 249.99 to 250 for simplicity 
250*1.04=260 or 259.9975 if you want to be technical

How do i solve to get the parallel equation

Answers

Two lines are parallel if they have the same slope. For example, the line 4x – 5y = 12 has a slope of m = 4/5. The slope of every line parallel to this line would have to be m = 4/5.

There are three steps required to find the parallel equation. I've attached a sample equation to illustrate these steps.

Step 1: Find the slope of the line.
Step 2: Use the slope to find the y-intercept.
Step 3: Use steps 1 and 2 to write the answer.
A parallel equation has the same slope but a different Y intercept than the other equation. To solve for it, the best way is to use y-y1=M(x-x1) with Y1 being your y coordinate of a given point, M being the same slope, and X1 being the X coordinate of the point.

5/7-2/5=

Answers

If you would like to calculate 5/7 - 2/5, you can do this using the following steps:

5/7 - 2/5 = 25/35 - 14/35 = (25 - 14) / 35 = 11/35

The correct result would be 11/35.
the answer is 11/35
