Step-by-step explanation:

2/3y +v = x

2/3y = x - v

y = (x - v)/(2/3)

y = 3(x-v)/2

y =3/2(x - v)

Answer:

y = 3/2( x-v)

Step-by-step explanation:

2/3y + v = x

Subtract v from each side

2/3y + v-v = x-v

2/3y = x-v

Multiply each side by 3/2

3/2 *2/3y =3/2( x-v)

y = 3/2( x-v)

Can someone explain how to solve for x?

alina1380 [7]

Answer:

x=11

Step-by-step explanation:

Notice that the first diagram is similar with the second diagram with ratio 1:2

Ex: Side length of JK is 6 and NP being 12, 6:12→1:2

You can conclude that x:22 needs to follow the ratio of 1:2

Thus, x=11

Two cards are drawn without replacement from a standard deck of 52 playing cards. What is the probability of choosing a red card

joja [24]

Answer: $\dfrac{3}{51}$

Step-by-step explanation:

Given : The total number of cards in a deck = 52

Number of red cards = 26

There are two types of red cards : diamond and heart.

Number of diamond cards = 13

The probability that the first card is a diamond :-

$\dfrac{13}{52}=\dfrac{1}{4}$

Since diamond is also a red card.

Now, the total cards left = 51

The number of red cards left = 12

The probability that the second card is a red card (without repetition) is given by :-

$\dfrac{12}{51}$

Now, the probability of choosing a red card for the second card drawn, if the first card, drawn without replacement, was a diamond :-

$\dfrac{1}{4}\times\dfrac{12}{51}=\dfrac{3}{51}$
