Answer: 0 < x < 5.6
Step-by-step explanation:
The sides of triangle:
Any two sides added together have to be larger than the third side
So:
2.8 - 2.8 < x < 2.8 + 2.8
0 < x < 5.6
Answer:
3x^2-4x+20/x^2-5x .
Step-by-step explanation:
The given rational expression is:
3x/x-5 - 4/x
Hence to find the difference of the rational numbers we have to take the L.C.M of the denominators:
Thus the L.C.M of x-5 and x is (x-5)(x) and then solve for the numerator:
x(3x) - 4(x-5)/(x-5)(x)
Now solve the numerator and denominator:
3x^2-4x+20/x^2-5x
Thus the answer is 3x^2-4x+20/x^2-5x ....
Answer:
After how many years is the fish population 60?
x=2.71 years
Step-by-step explanation:
The fish population increases by a factor of 1.5 each year. We have the equation that represents this situation
Where x represents the number of years elapsed f(x) represents the amount of fish.
Given this situation, the following question could be posed
After how many years is the fish population 60?
So we do and solve for the variable x
Observe the solution in the attached graph
Answer:
23 or more chairs.
Step-by-step explanation:
There are 5 tables to start. Each tables is 450 dollars.
5x450=2250
4500-2250=2250
2250(money still need to be made) divided by 100(the price of a chair)=22.5
Since you can't have a half of a chair but you cant have any less, you round it up to 23 chairs. The answer is 23 or more chairs.
