2x+5= -25 and -3m-6= 40 <br><br> What is the product of x and m?
ivanzaharov [21]

Answer:

Step-by-step explanation:

2x+5= -25 .........(1)

and -3m-6= 40........(2)

Considering (1): 2x+5= -25

2x = -25 - 5

2x = -30

x = -30/2

x = -15

Considering (2): -3m-6= 40

-3m = 40 + 6

-3m = 46

m = -46/3

Product of x and m = (-15) × (-46/3)

= -5 × -46

= 230

What is the probability of drawing a black ace followed by a heart out
Verdich [7]

Correct option C) 0.98%

<u>Step-by-step explanation:</u>

We know that  , there are 2 black ace cards out of 52 cards in a deck & 13 hearts out of 52 cards . Here we have to tell What is the probability of drawing a black ace followed by a heart out  of a deck when the cards aren't replaced . Let's find out:

Firstly , a black ace is drawn , so probability :

⇒ P(Black) = \frac{2}{52}

Now , A heart is drawn out of 51 cards ( as one black ace is already drawn !):

⇒ P(Heart) = \frac{13}{51}

So , Probability of occurring both events is :

⇒ P(Black)(P(Heart))

⇒ \frac{2}{52} (\frac{13}{51} )

⇒ 0.0098

Percentage = 0.0098(100) = 0.98%

Therefore , Correct option C) 0.98%
