1 in 4

4 suits, each with the same number of cards. 1/4 of the cards are diamonds, so theres a 1 in 4 chance of drawing one.

It is usually 1/52 or something like 1/4. It actually a random chance.

PLEASE HELP!!!<br><br><br>Solve.<br><br><br><br>a - 2b = 2<br>a + b = 2 ( b + 3 )
wolverine [178]

a-2b=2.........(1)

a+b=2(b+3)

a+b=2b+6

a-b=6.......(2)  

a-2b= 2

a-b= 6

Eliminate y  

multiply (1)by -1  

Multiply (2) by 2  

-a+2b=-2

2a-2b=12

Add the two equations  

a = 10

plug value of a in (1)  

1a +-2b=2

10+-2b=2

-2b =2

-2b =-8

b=4.00

Hope this helped:)

The perimeter of a rectangular garden is 9696 meters. The length is 6 meters longer than twice the width. Find the dimensions of
nalin [4]

length = 3234 m and width = 1614 m

let the width = w then length = 2w + 6

Perimeter = 2 ( length + width )

               = 2 (2w + 6 + w ) = 2 ( 3w + 6 ) = 6w + 12

given perimeter = 9696 the equating gives

6w + 12 = 9696

subtract 12 from both sides

6w = 9696 - 12 = 9684

divide both sides by 6

w = \frac{9684}{6} = 1614

width = 1614 m and length = (2 × 1614 ) + 6 = 3234 m
