2 + 2 + 2 = 6                    (6 x 6 ) / 6 = 6

(3 x 3) - 3 = 6                    7 - (7 / 7) = 6

4 + 4 - √4 = 6                  8 - √ (√( 8 + 8))  =  8 - √√(16)   = 8 -√4 = 8 - 2  = 6

5 + (5 / 5)= 6                    (√ 9  x √9 )  - √9 = 6    

Isn't it funny, rosala???....you ditch school because you're tired.....and then, when your mom lets you stay home...... suddenly, you aren't tired, at all....LOL!!!

Mirishikiari  = Chris  = "CPhill"

Yep....

Melody has provided a good answer....here's another way.....

First, divide 84 by 3 = 28

Add 2 to 28  = 30   and subtract 2 from 28  = 26

And there are your answers.....26, 28 and  30 ...!!!!

I'm voting for "Pygmy"..........

3 1/2 x 5/6=

Converting the mixed number to an "improper" fraction, we have 3 + 1/2  = 7/2

Now, just multiply 7/2 x 5/6 = 35/12 .....in mixed number terms, we have 2 + 11/12

OK....post your problems, and we'll see what we can do for you........

I'm assuming this is supposed to be ..  x^2+y^2=5   2y+x=3  ..if so......

Using the second equation we can rearrange it to x = 3-2y  ... and substituting this into the first equation, we have

(3 - 2y)^2 + y^2 = 5     simplify

4y^2 -12y + 9 + y^2 = 5     subtract 5 from both sides and simplify

5y^2 -12y +4 = 0

(5y -2) (y -2) = 0    and setting each factor to 0, we have that y =2/5 and y =2

And using x = 3-2y  we have that x = 3-2(2/5) = 11/5   and  x = 3-2(2) = -1

So, our solutions are  (11/5, 2/5) and (-1, 2)

BTW......these are the intersection points of a line [2x + y =3] and a circle [x^2 + y^2 = 5] centered at the origin with a radius of √5

A proportional relationship between the number of pounds of potatoes (x) and the price in dollars (y) is graphed, and the ordered pair (4, 3) is on the graphed line. Part A: What is the price of 1 pound of potatoes? Show your work, including the proportion you used to determine the price. (8 points) Part B: What does the ordered pair (8, 6) on the graph represent? Explain in words. (2 points)

The point (4,3) means that 4 lbs. of potatoes = $3. Therefore, we have:

4 lbs / $3  = 1lb / x       cross-multiply

4x = 3      divide by 4

x = 3/4 dollars = $.75 per pound

The point (8,6) means that 8 lbs. of potatoes = $6.
