Step-by-step explanation:
n=n/2 +7
Answer:5
Step-by-step explanation:(5) Is not changing the value at all so the answer is simply 5
This would practically be very reliable of course. We can see in the sentence above that y and x, and x and y are both depending on each other. So, now that this has been considered, we can see that whenever "x" would be a certain number, this would show you that "y" would also be a certain number, and depending how much "x" or "y" would move, it would also change these variable no matter how they move.
This would be a matter of division. As we can see above on how 9 and 15 could be divisible down the line as they multiply.
Therefore, we would then see how many times would "x" which is 9, how many times that would go in 33.
Let's start!

We take this "3.6" away from this, and we would plug it into "y".
We then do the following:

Therefore, when "x" = 33, "y" would then equal 55.
Your answer:
<span>We know that the runner completed her first race in 17.8 seconds and that she completed her second race in 16.9 seconds. Then the difference between the first race and the second race is .9 seconds. Now we divide .9 by 17.8 and multiply by 100 to get the percent decrease. We get 5.06%. The percent decrease in her time is 5%.</span>
Answer:
7 feet and 24 feet
Step-by-step explanation:
In the right triangle, the hypotenuse is 25 feet long. The area of this triangle is 84 square feet.
Let x feet and y feet be the lengths of triangle's legs.
By the Pythagorean theorem,

The area of the right triangle is half the product of its legs, thus

Solve the system of two equations:

From the second equation:

Substitute it into the first equation:

The length of the leg cannot be negative, so
