Step-by-step explanation:

First, there are two pounds and each pound is 85 cents. So, multiple 85 cents by 2.

That, will come put to $1.70

Now we still have .75 left of a pound. It will be best to figure out how much a quarter pound will cost because 3 of how much one quarter pound cost is .75 pounds. So, in order to find that out we know .85 cents is one pound so we will have to dived that by 4.

That will come out to, .21 cents

Now, that is for one quarter pound. we have to find .75 pounds. So, multiple the quarter pound by 3.

That will come out to, .63 cents.

.63 is for .75 of a pound. So, the last thing we have to do is take our .75 pound and add it to our 2 pound one that we solved for earlier.

That will come out to, $2.33

So you're answer will be $2.33 for 2.75 pounds.

Write 45/72 in the simplest form

Oliga [24]

Hi!

In my opinion, the easiest way to solve a problem like this is to find the greatest common factor (GCF) of the numerator and denominator and then divide both numbers by the GCF.

So first we need to find the factors of 45 and 72 and find the factor that has the most value that the two numbers both have.

45: 1, 3, 5, 9, 15, and 45

72: 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72

It looks like the GCF is 9. Now we have to divide 45 and 72 by 9.

45 ÷ 9 = 5

72 ÷ 9 = 8

So the correct answer should be:

$\frac{45}{72} = \frac{5}{8}$

Hope this helps :)

What is the solution of x=2+ square root x-2?

alex41 [277]

So I'm going to assume that this question is asking for non extraneous solutions, or solutions that are found in the equation and are valid solutions when plugged back into the equation. So firstly, subtract 2 on both sides of the equation:

$x-2=\sqrt{x-2}$

Next, square both sides:

$(x-2)^2=x-2\\(x-2)(x-2)=x-2\\x^2-4x+4=x-2$

Next, subtract x and add 2 to both sides of the equation:

$x^2-5x+6=0$

Now we are going to be factoring by grouping to find the solution(s). Firstly, what two terms have a product of 6x^2 and a sum of -5x? That would be -3x and -2x. Replace -5x with -2x - 3x:

$x^2-2x-3x+6=0$
