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.
Step-by-step explanation:
Mercury is very different than Earth. I think Mercury is a very hot planet, and because of the gravity and other conditions - look these up online - Humans and other life on Earth cannot live on Mercury, much less visit without being fully protected. Temperature on Mercury 426 degrees Celsius, about 800 degrees fahrenheit - very hot. You would want your space craft to completely protected from these temperatures, think of some materials you could use, and how thick you would need them? What material protects from heat? As far as vacuum conditions, and gravity, you will need to have that included as well.Maybe you would just wear a type of clothing to protect against bumping around in your space craft since you will not have gravity, you will also want to think about food!

Answer:
B
Step-by-step explanation:
Once you subtract both sides, the 4 is gone then the 10 is subtracted into a 6. You go to the 3x, and just like what you did to the 4 you do the opposite and divide the 3 by itself and the 6 by 3 as well.
