using the associative property, 9 + (6 - 3) = (9 + 6) + 3. is 9 - (6 - 3) equal to (9 - 6) - 3? explain.

goldfiish [28.3K]

No because it only works with addition and multiplication

9+(-6-3)=(9-6)-3 is true tho

9-(6-3)=9-(3)=6
(9-6)-3=(3)-3=0
so not equivilent

Find the real solutions, if any, of the following equation. Use the quadratic formula. x^2 square root 2x -5 =0

JulijaS [17]

Answer:

x = 0 or x = 5/2

Step-by-step explanation:

Solve for x over the real numbers:

x^2 sqrt(2 x - 5) = 0

Split into two equations:

x^2 = 0 or sqrt(2 x - 5) = 0

Take the square root of both sides:

x = 0 or sqrt(2 x - 5) = 0

Square both sides:

x = 0 or 2 x - 5 = 0

Add 5 to both sides:

x = 0 or 2 x = 5

Divide both sides by 2:

Answer: x = 0 or x = 5/2

I need help with b and c

mr_godi [17]

B. Just find the percentage to see if it is correct
$\frac{24.5}{73}$
It equals about .3356, but multiply it by 100 to get its percentage which is about 34%. So yes it is correct.

C.
$\frac{reading}{watching \: tv} \frac{3}{12}$
Simplified would be a ratio of
$\frac{1}{4}$
So they would be incorrect

Tell me if it helps by thanking it!!

An election ballot asks voters to select five city commissioners from a group of thirteen candidates. In how many ways can this

anzhelika [568]

This can be solved using permutations.You can get more into this online or just accept a quick answer here.

Since there are certain roles to be filled this is a permutation.

You need a somewhat smart calculator for this.

If I remember this right you'd type in the number of people you are choosing from, P , and then the places you are trying to fill.

So it should look like this:

13 P 5

You can find where permutations and combinations are in your calculator using a handbook or the internet but usually it looks like nPr for permutation or nCr for combination.
