500/19 = 26.315789474

about 26 minutes OR about 26 minutes and 18 seconds

4(2x+1)

|-3x| = 18

Multiply through to get:

20 + 6v -20 > 2v

6v >2v      Subtract 2v from both sides

4v > 0       Divided both sides by 4

v > 0

x = 6 or  -6

Since the garden is a rectangle, we know one side will measure 45 feet  (the same as the opposite side...which is the lake frontage)....  to know the WIDTH, (of which there will be TWO lengths of fence) we will need to know:

A.  Total amount of fencing

the LENGTH of the lake and the house measurements are irrelevant to the size of the graden.

Hey here a Question for Rearranging Formulae:

(find x)

for what value of x are f(x)= 4x+9 and g(x)= x^2 +13 equal

Because they teach us stuff that we will probably never us in your  life. 

From your question there are 1500 types of potatoes that are NOT from Peru

1500/4500   is the liklihood it will not be from Peru  = 1/3   or  1 out of three chance.

7(3-8)2 = 7(-5)2 = -35(2) = -70

1.00 dollar = 100 cents     100 cents/6badboys = 16.67 cents each

Let x  = .888888.....

   10x = 8.88888....

10x - x  = 9x  = 8

                 x   = 8/9      = .88888.....

(7/12)  /  (4/1)    =   7/12  x 1/4  = 7/48

Simplify the following:
((-3)/2)^2+3×(-3)/2-10

3×(-3)/2 = (3 (-3))/2:
((-3)/2)^2+(3 (-3))/2-10

3 (-3) = -9:
((-3)/2)^2+-9/2-10

((-3)/2)^2 = (-3)^2/2^2:
(-3)^2/2^2-(9)/2-10

(-3)^2 = 9:
9/2^2-(9)/2-10

2^2 = 4:
9/4-(9)/2-10

Put 9/4-(9)/2-10 over the common denominator 4. 9/4-(9)/2-10 = 9/4+(2 (-9))/4+(4 (-10))/4:
9/4+(2 (-9))/4+(4 (-10))/4

2 (-9) = -18:
9/4+-18/4+(4 (-10))/4

4 (-10) = -40:
9/4-(18)/4+-40/4

9/4-18/4-40/4 = (9-18-40)/4:
(9-18-40)/4

9-18-40 = 9-(18+40):
9-(18+40)/4

9-58 = -(58-9):
-(58-9)/4

Answer: |(-49)/4

(1/2)^8 =1^8/2^8 =1/256

You could break it up into 8 parts: 1/2 x 1/2 x 1/2... and so on. Or you do it an easier way. (1/2)^8 is multipling each component 8 times. Like 1^8 / 2^8 and that equals 1/256
