<span>The equation is pretty straightforward. Basically, if 10^13 bacteria multiplies in 100 hours. We seek to know how many bacteria multiply per hour.
So if 10^13 bacteria mulitply in 100 hours
Then X bacteria multiply in an hour.
Hence X bacteria * 100 hours = 10 ^13 bacteria * 1 hour.
X = 10 ^13 * 1 / 100= 10^(13-2) 10^11. Basically, 10^11 bacterias multiply in an hour.</span>
He brought 6 sticky pads and 6 envlopes because 6x3= 18
After paying for the flat rate, she has 10-3.25=6.75 left.
With 6.75 she can go for 6.75/0.75 = 9 miles
Note: solving by reasoning is often faster than mechanically forming an equation.
The indicated points are (1,1) and (2,3). Slope is change in y over change in x,
m = (3 - 1)/(2 - 1) = 2/1 = 2
Answer: C) 2
For this case we have the following inequality:
To find the solution we follow the steps below:
We apply distributive property on the right side of inequality:
Adding 13 to both sides of the inequality we have:
We subtract 6x on both sides of the inequality:
Thus, we have that any value of "x" makes the inequality fulfilled. Thus, the solution is given by all real numbers.
Answer:
The solution set is (-∞,∞)
