Answer:
Option B is correct
No solution
Step-by-step explanation:
Given the system of equation:
......[1]
......[2]
We can write equation [2] as
y =8-x
Substitute this in [1] we have;
Using distributive property:
Combine like terms;
false.
⇒ the system of equations does not have any solution.
Using Graphing calculator:
You can see the the graph of the system of equations as shown below:
The graph of the lines do not intersect, so the graphs are parallel and there is no solution.
Answer:
80 gummy bears are in 4 servings.
Step-by-step explanation:
2 servings=40 gummy bears
3 servings=60 gummy bears
<u>40</u>+20=<u>60</u>
Add 20 gummy bears for every serving.
5 servings=100 gummy bears
100-20=<u>80 gummy bears are in 4 servings</u>
OR you can also do:
40÷2=20 gummy bears are in each serving
So, 4x20=<u>80 gummy bears are in 4 servings</u>
