We are given the equation
to solve the equation we follow the following steps:
i) add 1 to both sides:
ii) multiply both sides by -2:
5x-8 = -14
iii) add 8 to both sides:
5x=-6
iv) divide both sides by 5:
x=-6/5
Answer:
x=2 x=-2
Step-by-step explanation:
x² + 2x - 4 = 2x
Subtract 2x from each side
x² + 2x-2x - 4 = 2x-2x
x^2 -4 = 0
Factor
We know this is the difference of squares
(x-2)(x+2) =0
Using the zero product property
x-2 =0 x+2 =0
x=2 x=-2
I am guessing you mean quantity instead of quality so in a year there is 8760 hours, so just take the 33,300 and divide it by 8760.
And you should get something like 3.801 people per hour
It is given in the question that, the swimming pool had 2.5 million liters of water in it. Some water evaporated, and then the pool only had 2 million liters of water in it.
So amount of water evaporated is
And percentage of water evaporated is
Therefore 20% of water evaporated .
Answer:
x=y/m-y1/m+x1
Step-by-step explanation:
You have to isolate the variable by dividing each side by factors that dont contain the variable.
