A table top would be a good representation of a plain because it is a flat surface, and isn't a 3D object, if that makes sense. A box wouldn't be a plane because it has 6 different sides but a table only has one side and one plane. hope this helps :)
Answer:
1) x=1/2-y/2-3z
2)x= 16/3- 2y/3- 5z/3
3)x= 11/7- 3y/7+ 4z/7
Step-by-step explanation:
isolate the variable, to do that divide each side by the factors that don't contain the variable
If you are asking how to find the square feet of the "weirdly shaped pirate money" you'd need to multiply the length and width. So:
11/12 * 3/4 = 33/48
So the answer is 33/48 square feet
If you are not asking for this answer word your question better please.
Use y=mx+b
m = 4
x = 0
y = -1
-1 = (4)(0) + b

Multiply
Joys age is x
x + (x-4) = 74
2x = 78
x = 39
joy is 39 years old
