Since you have two numbers that have a (x) at the ends of them, you add those first then add seven which will end up being 9x+7
Answer: 99% decrease
Step-by-step explanation: Since the number changes from 6,000 to 60, we know that it's decreasing. Now to find the percent decrease, we divide the amount of change by the original number.
The amount of change is the difference between 6,000 and 60 and the original number is 6,000.
6,000 - 60 is 5,940 so we are left with
and dividing 6,000 into 5,940 gives us 0<em>.</em>99.
Finally, since the problem is asking us for the <em>percent</em>, we write 0.999 as a percent by moving the decimal point 2 places to the right to get 99%.
So when a number changes from 6,000 to 60, it has decreased by 99%.
Answer:

Step-by-step explanation:
Since the second equation is fully simplified and we know what x equals, we plug the entire equation of x in for x in the top equation:

Now solve for y.

Now plug y back into the bottom equation and solve for x.


The total amount of profit that he was able to gain out of his 450
shares is 2,205. In the problem, it states that for ever share he earns
$5 dollars each.in order to derive the total amount of profit he got
from his shares, we multiply 450 shares and $5.
so, 450*5 is equals to $2,205.
