For this case what we have to take into account is the following variable:
x = represent the unknown number
We now write the following inequality:
"four times the sum of number and 15 is at least 20"
4 (x + 15)> = 20
We clear the value of x:
(x + 15)> = 20/4
(x + 15)> = 5
x> = 5 - 15
x> = - 10
The solution set is:
[-10, inf)
Answer:
all possible values for X are:
[-10, inf)
Statistics is not an exact science, meaning that with any answer, there will be variance. This is because the sample size used to obtain values is always smaller than the population being studied.


Subtract the answer of the division problem from the sum of 33 and 7. Your answer would be:
40 - 5
Simplified:
35
Using the formula for the volume of a cube, it is found that the expression which gives the ratio of the side length of Cube A to the side length of Cube B is:

Which means that option E is correct.
The <em>volume of a cube</em> of side length l is given by:

For Cube A, the volume is of 9 cubic inches, hence:

![l_a = \sqrt[3]{9}](https://tex.z-dn.net/?f=l_a%20%3D%20%5Csqrt%5B3%5D%7B9%7D)


For Cube B, the volume is of 5 cubic inches, hence:

![l_b = \sqrt[3]{5}](https://tex.z-dn.net/?f=l_b%20%3D%20%5Csqrt%5B3%5D%7B5%7D)

Then, the ratio is:
