Answer:
d) 5/3 x
Step-by-step explanation:
You substitute a for 2c and b for 5d, so your equation will look like this:
c/d - 2c/5d = x
Then you just simplify into x by making c/d into 5c/5d so you have a common denominator.
5c/5d - 2c/5d = x
3c/5d = x
5/3 is your answer
Answer:
8926 bacteria
Step-by-step explanation:
We have been given that the population of a bacteria in an experiment has been increasing by 80% each day. There were 25 bacteria at the beginning of the experiment. We are asked to find the number of bacteria in 10 days.
We will use exponential growth formula to solve our given problem.
, where,
y = Final amount
a = Initial amount,
r = Growth rate in decimal form,
x = Time.
Upon substituting our given values in above formula, we will get:
To find number of bacteria in 10 days, we will substitute in our formula as:
Therefore, there will be approximately 8926 bacteria in 10 days.

Do i need to explain ??????
The sum of the sides of a triangle is equal to 180º.
The three angles will be: 3x,4x and 5x.
we can suggest the following equation:
3x+4x+5x=180
12x=180
x=180/12
x=15
The angles would be:
3x=3(15)=45
4x=4(15)=60
5x=5(15)=75
Answer: the highest angle would measure 75º.
