Answer:
x=4
Step-by-step explanation:
Line segments VW and UX should be equal, so you can set the equal to each other.
3x=12
x=12/3
x=4
It is true, because the only number that is E and F is 4 and 4 is also a whole number
Answer:
I would think it's X= -29 1/3
Step-by-step explanation:
You have 20 1/3 already, and to get to a negative when you have a positive number, to the positive you would need to add a larger negative. (If that makes any sense, it's hard to explain.) So you have to get rid of the 20 1/3 and you have to get to -9, so I would add a 9 to 20 1/3 to get 29 1/3, and make that number negative because then it will cancel the positive out. Making it -9.
Answer:
A. Used to keep track of very large and very small numbers during mathematical calculations.
Step-by-step explanation:
Some very large and small numbers are not easily represented in mathematical calculations. Using scientific notations help us to represent very large and small numbers to the power of 10.
