Let <em>x</em> be the amount of salt in the solution.
At day's end, the concentration of salt in the beaker is
<em>x</em> / (4 L) = 0.08 = 8%
Solve for <em>x</em> to get
<em>x</em> = 0.08 (4 L) = 0.32 L
So at the beginning, the concentration of salt in the beaker was
(0.32 L) / (5 L) = 0.064 = 6.4%

Step-by-step explanation:
HOPE THIS HELPS :)
So for one 3.25x5= 16.25 then 16.25x2 = 32.50. So 40 dollars will be enough
Answer:
which one?
Step-by-step explanation:
-38(-3) = 114
-72/(-12) = 6
-9 x 23 = -207
-150/5 = -30
564 / -4 = -141
<h3><u>Solution:</u></h3>
Given that, we have to find each product or quotient
<em><u>-38(-3)</u></em>
It is a product, so we have to find product value

<em><u>-72 / (-12)</u></em>
It is division, so we have to find the quotient

<em><u>-9 x 23</u></em>
It is a product, so we have to find product value

<em><u>- 150 / 5</u></em>
It is division, so we have to find quotient

<em><u>564 / -4</u></em>
It is division, so we have to find the quotient
