Back in my old days, everyone HATED fractions!! So in order to rid of them, you have to multiply them with the greatest common factor in all of them (GCF). So it would look like this: GCF of 3,6, and 6 would be 6. Once you know that, you multiply it to the whole equation. 6(1/3z +1/6 = 5/6) Then do the math and you should be left over with no fractions at all. 2z+1=5 If you don't know your algebra 1 skills, you must move the numbers to one side and keep the variables on the other side -> 2z=4 •Divide by 2 on each side z=2 will be the answer if you want to practice :) The answer to the question -> {multiply by 6}. If it is decimals, you MUST want to take away that annoying dot right there just by multiplying by 10,100,1000,10,000 and so on for the whole equation. Pretend we have 1.307 We multiply by 1000 because 7 is in the thousandths place so you get a whole number. -> 1307! So the problem asks 3.7 + 2.75k = 27.35 You see that the GCF can be only by 10, 100 and so on because you don't want the dots. Then the GCF in this case would be 100. So {multiply by 100}. 100(3.7 + 2.75k = 27.35) Changed to 370+275k=2735 •Subtract the numbers 275k=2355 •Divide k=8.6 Hope this helps!

Answer:

Given equation:

y = 10x - 32

To find the y-intercept, evaluate the equation with x = 0:

y = 10*0 - 32
y = 0 - 32
y = -32

To find the x-intercept, evaluate the equation with y = 0:

0 = 10x - 32
10x = 32
x = 32/10
x = 3.2

X = 1 + root 2 , find the value of (x - 1/x )^3

steposvetlana [31]

Answer:

$(\sqrt{2})^3$

Step-by-step explanation:

Given the expression

$(x - \frac{1}{x} )^3$

Simplify

$(\frac{x^2-x}{x} )^3$

Given that x = 1+√2

Substitute

$(\frac{(1+\sqrt{2} )^2-(1+\sqrt{2} )}{1+\sqrt{2} } )^3\\=( \frac{1+2\sqrt{2} +2 - 1 - \sqrt{2}}{1+\sqrt{2}} )^3\\= (\frac{\sqrt{2}+2}{1+\sqrt{2}})^3 \\Rationalize\\= (\frac{\sqrt{2}-2+2-2\sqrt{2}}{1-2})^3 \\=( \frac{-\sqrt{2}}{-1})^3 \\= (\sqrt{2})^3\\ \\$

Small library contains 700 novels. how many ways can You check out three novels

schepotkina [342]

The first book you select can be any one of 700.

. . . For each of those ...

The second book can be any one of the other 699.

. . . For each of those ...

The third book can be any one of the remining 698.

The total number of ways to gather three books from the shelves into your hands is (700 · 699 · 698) = 341,531,400 ways .

BUT ...

When you bring three books to the check-out counter, Marian the Librarian doesn't know in which order you took them down off the shelves. You could have gathered the same three books in (3 · 2 · 1) = 6 different ways.

So, even though there are 341,531,400 ways to gather up three books, there are only (341,531,400 / 6) = 56,921,900 different GROUPS of three books that you can choose to take home.
