Jesse Owens was an American athlete.

Answer:

If it's all five then just round to the bigger ten , hundred or thousand. like if it's five then rounded to the nearest ten would be 10 .if it's 55 rounded to the nearest hundred is 100. if the number is 555 rounded to the nearest thousand is one thousand. remember if it's five or more round it to the bigger ten, hundred or thousand. if it's 4 or smaller then round it to the smaller ten ,hundred or thousand.

I HOPE IT CAN HELP:)

  x + y = 3
- x        - x
        y = -x + 3

  y - y₁ = m(x - x₁)
y - (-1) = -1[x - (-1)]
  y + 1 = -1(x + 1)
  y + 1 = -1(x) - 1(1)
  y + 1 = -x - 1
     - 1         - 1
       y = -x - 2

The answer is B.

A 5-gallon jug of cleaning solution contains 6% bleach. How much pure water should be added to it to dilute to 4% bleach?
mihalych1998 [28]
Let's bear in mind that 5 gallons with a solution of 6% bleach, contains some water plus some bleach, how much bleach?  well, is just 6% of 5 gallons or namely (6/100) * 5 gallons, or 0.30 gallons.

if we use "x" gallons of water, well pure water has no bleach, so is 0% bleach, and it has a (0/100) * x or 0x gallons of bleach.

the mixture will be say "y" gallons, and is 4% bleach, so (4/100) * y is 0.04y gallons in the mixture of bleach.

\bf \begin{array}{lcccl}
&\stackrel{gallons}{quantity}&\stackrel{\textit{\% of bleach}}{amount}&\stackrel{\textit{gallons of bleach}}{amount}\\
&------&------&------\\
\textit{pure water}&x&0.00&0x\\
\textit{6\% solution}&5&0.06&0.3\\
-----&------&------&------\\
mixture&y&0.04&0.04y
\end{array}
\\\\\\
\begin{cases}
x+5=\boxed{y}\\
0x+0.3=0.04y\\
---------\\
0.3=0.04\left( \boxed{x+5} \right)
\end{cases}
\\\\\\
0.3=0.04x+0.2\implies 0.1=0.04x\implies \cfrac{0.1}{0.04}=x\implies 2.5=x
