Answer:
C
Step-by-step explanation:
We see that we can factor out 2x from the equation! So our equation becomes 2x(x-2) = 0.
Since the only way for things to multiply to equal to zero is if at least one of the numbers is 0.
So if x-2 is the 0, then x = 2.
If 2x is the 0, then x = 0.
So our answer is C. 0,2
Answer:
Step-by-step explanation:
Let that number be 
. We can build an equation, and solve for .
less than half of is 
.
more than is 
.
We are given that the two quantities are equal, so we have that 
.
Adding to both sides gives 
.
Multiplying both sides by gives 
.
Subtracting 
from both sides gives 
.
Multiplying both sides by 
gives 
.
So, the number is 
and we're done!

Answer:
x = 125
Step-by-step explanation:
x = 160 - 35
x = 125
Answer: 360g
120 --> 10
x ---> 30
120*30=10*x
3600= 10*x
x= 3600/10
x= 360
