Answer:
(x, y) = (-6, -4)
Step-by-step explanation:
The solution can be found quickly using a graphing calculator. It is the point of intersection of the two lines.
_____
If you like, you can solve the system algebraically. The second equation can be rewritten to give ...
y = x +2
Substituting this into the first equation gives ...
5/3x -2(x +2) = -2
-1/3x -4 = -2
Adding 4 and multiplying by -3 gives ...
x = -3(-2+4) = -6
Then our equation for y tells us ...
y = -6 +2 = -4
The solution is (x, y) = (-6, -4).
Answer:
4 1/2 cup servings
Step-by-step explanation:
A= -1
You add the 6a and 5a.
Your equation is then 11a= -11
At this point you divide each side by 11 to get "a" by itself.
Answer:
20s=m
Step-by-step explanation:
I really don't understand it that well but all that I can is that s can represent students that went on the trip, and each student's ticket cost is 20$, so 20*s=20s, but we are taking m as the total money collected, so we can end up saying that 20s=m, hope u understood :)
Example:
5/20 x 100 you put whatever fraction your looking for into calculator and multiply by 100
