Solve for X and y PLEASE GIVE FULL EXPLANATION HOW YOU GOT IT

Dennis_Churaev [7]

Answer:

(1, -1)

Step-by-step explanation:

we isolate y in the first equation

2x+y=1

-2x. -2x

y=1-2x

and now we fill y into second equation

4x-2(1-2x)=6

4x-2+4x=6

8x-2=6

+2 +2

8x=8

/8 /8

x=1

and now to find y we insert x

2(1)+y=1

2+y=1

-2. -2

y= -1

hopes this helps

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 :-

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

If on a scale drawing 24 inches equals 10 ft. what does 1/8 inches equal

OLga [1]

Answer:

$\large\boxed{\large\boxed{(5/96)ft\approx 0.052ft}}$

Explanation:

1. Use the scale ratio to set a proportion with the unknown lenght.

$24inches/10ft=(1/8)inches/x$

2. To solve for x, use cross multiplication:

$24inches\times x=10ft\times(1/8)inches$

3. Divide both sides by 24inches:

$x=10ft\times(1/8)inches\times (1/24inches)$

4. Simplify:

$x=10ft/192=(5/96)ft\approx 0.052ft$
