Answer:
It is 64. Pls mark me as brainliest.
Step-by-step explanation:
You divide.
576÷9=64
576÷9
9÷9=1
64/1
or
64
There both the same.
<h3>
Answer: Choice B) 122%</h3>
==========================================
Work Shown:
A = 1250 is the initial amount
B = 2780 is the new amount
C = percent change = unknown for now
The formula to use is
C = [ (B-A)/A ] * 100
to calculate the percent change.
Basically we calculate the change (B-A) first and then divide that over the original amount A to compute the decimal form of the answer, which is then converted over to percentage form. The "100" tacked on at the end is what converts from decimal to percent form.
---------
C = [ (B-A)/A ] * 100
C = [ (2780 - 1250)/1250 ] * 100
C = (1530/1250)*100
C = 1.224 * 100
C = 122.4%
C = 122%
---------
The positive C value indicates we have a percent increase. If C were negative, then we'd have a percent decrease.
<h2>Steps:</h2>
So for this, we will be setting up a system of equations with the information we have:

Now we have our system of equations set up. Next, I will be using the substitution method to solve this system. So firstly, subtract y on both sides of the first equation:

Now, substitute x for (13 - y) in the second equation and solve for y as such:

Now that we have the value of y, substitute it into either equation to solve for x:

<h2>Answer:</h2>
<u>In short, the first number (x) is 8 and the second number (y) is 5.</u>
