Answer:
18/36 or 1/2
Step-by-step explanation:
There are 18 nickels, which is the numerator.
You add all the numbers together to get the denominator, which is 12+6+18=36.
Then, you put the two values in a fraction - 18/36
and simplify, to get you 1/2.
Answer:
x=18
Step-by-step explanation:
Hey There!
So if you did not know all of the angles in a triangle will add up to equal 180
So we use the equation
180=2x+3x+5x
and solve for x
step 1 combine like terms
2x+3x=5x
5x+5x=10x
so now we have
180=10x
step 2 divide each side by 10
180/10=18
therefore x = 18
hope this helps and if you have any more questions feel free to ask :)
Answer:
wastewater and fertilizer runoff
Step-by-step explanation:
Factors such as temperature, pH electrochemical (redox) potential, and the transparency of air and water can affect the chemical and physical characteristics of ecological systems. This are as a result of activities like climate change, water contamination, and changes in water runoff.
Wastewater and fertilizer runoff causes low amount of dissolved oxygen in water, which affect biological communities and cycling thereby resulting in chemical and physical states changes.
The square root is between 187 and 188
