Answer:

500 items

Step-by-step explanation:

plug the $320000 into C

320000=500x+70000

1. substract 70000 from both sides (always get rid of adding/substracting first)

320000=500x+70000

<u>-70000 -70000</u>

250000=500x

2. divide both sides by 500 (you divide both sides by whatever number is in front of x so you can isolate it)

<u>250000/500=500x/500</u>

500=x

there you go :D good luck and have a good day

If a math student Square both legs of a right triangle and the results were 441 and 400, what is the length of the hypotenuse of
kolezko [41]

Answer:

29 \\

Solution:

According to the Pythagorean Theorem, is that the square of the hypotenuse is equal to the sums of squares of the two legs in which if you take the square root of the sum you are going to get the actual length of the hypotenuse but the two legs are already squared so all you have to do now is sum them and take the square root of it.

\sqrt{441  +  400}  \\  \sqrt{841} \\ 29
