Answer:
36p +24
Step-by-step explanation:
Distribute by multiplying 4 to each part. So, you get 36p + 24
Answer:
Systems of equations equals (-1.5, 4)
Step-by-step explanation:
1. isolate the y in both equations
2. a. 4x+3y=6
3y=-4x+6
y=-4/3x+2
b.
2y=4x+14
y=2x+7
3. Solve the system of equations
-4/3x+2=2x+7
2=3 1/3x+7
-5=3 1/3x
-1.5=x
4. Solve for y by plugging x into one equation
y=2x+7
y=2(-1.5) + 7
y= -3+7
y=4
5. Systems of equations equals (-1.5, 4)

Answer:
<em>The probability of getting exactly 2 of the cards are spades out of 6 cards will be </em><em>0.315</em>
Step-by-step explanation:
6 cards are drawn at random from a standard deck of 52 cards.
The number ways 6 cards can be drawn from a deck of 52 cards will be,

In a deck of 52 cards, 13 cards are of spades. So drawing 2 spades out of 13 is,

As exactly 2 must be spades, so the remaining 4 cards must be drawn from other 39 cards of other suits. This can be done in,

The probability of getting exactly 2 of the cards are spades out of 6 cards will be,

Step-by-step explanation:
(2(x+y)÷(x+y)(x-y) )×(x+y÷(x^2+2×x×2y+2y^2)
2÷x^2+2y^2
