25 x² - 10 x = 0
5 x ( 5 x - 2 ) = 0
x = 0 and
5 x - 2 = 0
5 x = 2
x = 2: 5
x = 2/5
Answer: B ) x = 0 and x = 2/5
Answer:
The amount of salt required is 0.3685 grams.
Step-by-step explanation:
20.9% of 1 gram of salt is chlorine, which means the grams of chlorine in 1 gram of salt are
Now, to make 220 ppm solution, it must be that
where 
is the grams of chlorine required.
We rearrange the equation and solve for 
since 1 gram of salt has 0.209 grams of chlorine, 0.07702g of chlorine corresponds to
Thus the amount of salt required is 0.3685 grams.
Answer:
I think C is the answer .
Step-by-step explanation:
If (x-6) and (x-1) are the factors of function f then remainder of function f is 0.
(x-6)(x-1) = 0
Either,
x-6 = 0
x = 6
and
x-1 = 0
x = 1
so 6 and 1 are the zeros or roots of function f.
Answer:
$60.00=Y× X
Step-by-step explanation:
You know she makes $60 but you need to figure out how many hours she works and how much an hour she makes working.
Y-5=4(x+2)
y-5=4x+8
+5 +5
y=4x+13
is that what you are talking about?
