Answer by JKismyhusbandbae:
|x| - 2 > 0
|x| -2 + 2 > 0 + 2
|x| > 2
Answer: x < - 2 or x > 2
X + 3x = 12
(Or 4x=12)
the first x is the number of girls then the second x is the girls times 3, which is how many boys there are.
Answer:Well, I don't know what you got so I can't tell you if it is right.
If it works in both equations, it depends of whether your equations are set up correctly.
Here is how I would do this problem.
Let x = no. of hot dogs,y = number of sodas.
First equation is just about the number of things.
x + y = 15
Second equation is about the cost of things.
1.5 x + .75 y = 18
solve x+y = 15 for y y = 15-x substitute into second equation
1.5x + .75(15 - x) = 18
You should get the correct answer for number of hot dogs if you solve this correctly. Put your answer in the x + y =15 equation to get y. Then put both x and y into the cost equation and check your answer.
Hope this helps.
