Dear ZaireMcfalane33, if you subtract with fraction strips the answer will be smaller, but if you add with fraction strips the answer will be bigger.
Answer:
its b
Step-by-step explanation:
A. has mass and takes up space :)
The problem can be translated into an equation that is something like 4/5 + 3/x = 1/2
we cannot have x equal to zero because the number can be infinite.
So the LCD here is 10x, so multiply both sides by that to get:
8x + 30 = 5x
Subtract 5x and 30 from both sides:
3x = -30
divide:
x = -10
The solution isn't zero so there is a solution.
