So, in 4 days, the lake lost 3.5 liters, and you need to solve for how many were lost each day.
There are two ways to do this; one involves writing an equation, the other does not. It pretty much just depends what your teacher expects from you.
The easiest way is to simply divide 3.5 by 4; this will tell you how many liters were lost each of those four days.
The other way does the same thing, but a little more algebraically...
3.5 liters per day were lost- this can be written as a ratio: 3.5 liters/ 4 days.
You need to solve for x liters/ 1 day.
Since these are equivalent, you set them equal to each other:

From here, you can cross multiply to get 3.5=4x
Then simply divide both sides by 4 (to isolate the variable) and you get 1.5=x.
Since the variable x represented the number of liters lost in 1 day, you can write your answer as 1.5 liters.
So, the simple answer is: the average change in the water volume each day was 1.5 liters.

Given data
Columbia Mirror and Glass pays Frank Griffin $2570 monthly salary plus a 6% commission.
If sales is $77,900
Required
Frank's take home
Step two
let us find the expression used to determine Frank's take-home pay
let the total be y
y= 2570+ 6/100*77900
y=2570+0.06*77900
y=2570+4674
y=$7244
Answer:
5765760
Step-by-step explanation:
We will use the Fundamental Counting Principle to find the answer. Simply determine the number of choices for each position and multiply.
For the first choice there are 16 choices. Then, the number is reduced by 1 each time.
So to get the answer, we have to multiply the numbers below:
16 x 15 x 14 x 13 x 12 x 11
To find the value of x, and then find the angles of triangle RST, we first need to set up an equation equal to 180.
First, the equation = 180:
We have 31, x+4, and 3x+9.
What we can do is make an equation in which adds the angles to equal 180.
As so:
31 + x + 4 + 3x + 9 = 180
Combine like terms:
31 + x + 4 + 3x + 9 = 180
44 + x + 3x = 180
44 + 4x = 180
Now, we need to simplify this further by subtracting 44 from each side:
44 - 44 + 4x = 180 - 44
4x = 136
Next, to simplify this equation <em>even</em> further, we need to divide each side by 4 (Resulting in the x being alone on one side of the equation.)
4x / 4 = 136 / 4
x = 136 / 4
x = 34
Awesome! We now know that x = 34!
However, we are not completely finished with this problem. Let's continue.
To find the angles of S and T, we need to substitute 34 in for x:
S:
(x + 4)
(34 + 4)
38 <em>degrees</em>
T:
(3x + 9)
(3(34) + 9)
(102 + 9)
111 <em>degrees
</em>
<em />Amazing! We now can conclude all of the angles' measurements:
<em>R</em> = 31
<em>S</em> = 38<em>
</em><em>T = </em>111
Also, x = 34.
