Solve the following equation for all values of x: 10x^2 - 5x = 0
kirill115 [55]
Using the quadratic formula works but if you know there are 2 answers (highest power of problem tells you how many solutions) then
10x^2 = 5x
So either x = 0, giving 0=0.  Or divide by 5x
2x = 1
x = 0.5

There are 36 feet of ribbon in
Dafna11 [192]

Answer:

63 feet of ribbon

Step-by-step explanation:

First, you find the unit rate by dividing 36 by 12. That gets you 3 feet of ribbon per package. Since you need to find how many feet of ribbon are in 21 packages, you multiply 21 and 3. 21x3= 63

The first term of set R is 15. What is the median value of the set R, if for every term in the set, Rn = Rn–1 + 3?
morpeh [17]

Answer:

median=mean=\frac{R_{n-1}}{2}+9

Step-by-step explanation:

The first thing to identify is that this one is a consecutive set, meaning that the increment between each number is the same, in this case, an increment of 3 between each number, when sets have this type of behavior, and only on these cases, the mean and the median are the same, let's look at some examples:

[2, 4, 6, 8, 10, 12]

The mean would be:

mean=\frac{2+4+6+8+10+12}{6}=7

Since the number of elements is even, the median would be the average of the two middle terms:

median=\frac{6+8}{2}=7

As you can see mean=median

There is one more thing to help you in this exercise, for consecutive sets, the mean can also be calculated by the formula:

mean=\frac{x_{1} + x_{n} }{2}

Where x_{1} is the first term of the set and x_{n} is the last.

If we ran this formula with the set i used as an example:

mean=\frac{2+12}{2}=7.

So applying all of that to the set given we would have:

median=mean=\frac{15+R_{n-1}+3}{2} =\frac{R_{n-1}+18}{2} =\frac{R_{n-1}}{2}+9
