Let the amount of shells collected by Aaron be
and the amount of shells collected by Maria be
respectively. Then the following system of equations should be solved:
First of all, express
out of first equation:
Then, replace
in second equation with found expression and solve it:
Finally, replace
in first equation with found value and solve it too:
So, Aaron has found
7 shells while Maria has found
21.
Answer:
17 students
Step-by-step explanation:
Given:
There are some students playing soccer.
Five students decided to join the game and now there are twenty-two students playing soccer.
Question asked:

As given,
<u>After joining 5 more students, there are 22 students playing soccer, the equation will be:-</u>
Subtracting both side by 5
Hence, 17 students were originally playing soccer.
Answer: 58
Step By Step Explanation: it’s pretty simple all you have to do is take 468 and divide it by 8 and you if you get a decimal such as 48.5 it’s just the first numbers before the decimal
The answer is infinitely many solutions
If you divide the 2nd equation by 3, you get the first equation, meaning they are identical. That means that any value of x will be true, which means there are infinite solutions
The formula to find the rate of change is y2-y1/x2-x1
6-(-4)/-3-(-1)
=10/-2
=-5
