Answer:
89.375
Step-by-step explanation:
First, add up all the numbers. Your answer should be 715. Once you get that divide by the the total amount of numbers so you added up 8 numbers, meaning you would divide by 8. 715/8=89.375
Answer:
In a problem where you
calculate the "solution" to a "system of equations"
one of three things will happen....
#1) you end up with x=3 , or y=7 .. or something like that
if that happens then there is ONE SOLUTION
#2) you end up with 5=5, or 7=7 , or 0=0
in this case the lines are the same and you have "all real numbers" as the solution (there are an infinite number of solutions, the lines are the same line)
#3) you end up with 1=2, 0=5, 2=7, etc. this is impossible, there are no solutions ... the lines are parallel
Step-by-step explanation:
Answer:
x = (y - 4)/7
Step-by-step explanation:
Subtract 4 from both sides to get:
y - 4 = 7x
Then, divide both sides by 7 to get:
(y - 4)/7 = x

Answer:
Correct option: (C) 83%.
Step-by-step explanation:
It is provided that the toxicity level of a lake is found by dividing the amount of dissolved toxins the lake water currently has per liter by the maximum safe amount of dissolved toxins that the water can hold per liter and then converting it to a percentage.
Denote the variables as follows:
<em>x</em> = amount of dissolved toxins the lake water currently has per liter
<em>y</em> = maximum safe amount of dissolved toxins that the water can hold per liter
The amount of dissolved toxins per liter of water in the river is, <em>x</em> = 0.86 mg/lt.
The maximum safe amount of dissolved toxins that the river water can hold is, <em>y</em> = 1.04 mg/lt.
Compute the toxicity level of the river water as follows:
Thus, the toxicity level of the river water is 83%.
The correct option is (C).
