Answer:
straight line through (0,4) and (2,0), shade everything above it
Step-by-step explanation:
First solve the equality, which will give you a straight line.
Then check if the inequality (the > sign) means you have to shade the area above or below it.
2x + y = 4 can easily be solved by first taking x=0, then you find y=4, hence (0,4) is a solution.
Then take y=0, then you find 2x = 4 so x=2, hence (2,0) is a solution.
Plot these two points and draw a line through them.
Now, since 2x+y has to be larger than 4, all the points to the right and above the line are valid. So that's the area you have to shade.
I’m guessing you want to find out (n).
That’s what I did anyway.
The answer is: n=5
Step 1: Subtract 5n from both sides.

S=Steve. S+4=Kevin. S+s+4=26. Combine: 2s+4=26. Subtract 4: 2s=22. Divide by 2: s=11. Steve ran 11 miles. :)
Answer:
243
Step-by-step explanation:
Whe you have a result of several possible combinations you must put the number (in this case) of possibilities (3) to the number of quantities (5), another example would be a dice (6 options) two dices (36 options) and so on.
Answer:
