Answer:

There are 52 cards in a deck. The total number of outcomes possible when picking 2 cards and replacing them is 52 * 52 = 2704.

There are 4 10s and 4 aces so the total number of successful outcomes = 4 * 4 = 16.

Probability = 16 / 2704 = 1 / 169

Write the following equation, then solve. The difference of four times a number, x and 12 is 28

Alona [7]

Answer:

4x - 12 = 28

To isolate 4x, we add 12 to both sides:

4x - 12 + 12 = 28 + 12

4x = 40

Now we divide 4 from both sides:

x = 40 / 4

so x = 10

If x + 3y = 7 and x - 3y =7 , then find y<br><br> Please help me

telo118 [61]

Answer:

$x + 3y = 7 , x - 3y = 7 : y = , x = 7$

Step-by-step explanation:

$\left[\begin{array}{ccc}x + 3y = 7\\x - 3y = 7\end{array}\right]$

Isolate $x$ for $x + 3y = 7 : x = 7 - 3y$ :

Substitute $x = 7 - 3y$ :

$\begin{bmatrix}7-3y-3y=7\end{bmatrix}$

Isolate $y$ for $7 - 3y - 3y = 7 : y = 0$ :

For $x$ $=7-3y$

Substitute $y = 0$

$x=7-3 * 0$

$7 - 3 * 0 = 7$

$x = 7$

The solution to the system of equations are:

$y=0,\:x=7$

Hope I helped. If so, may I get brainliest and a thanks?

1/4(-12x+16) 10-3(-x-2)

Oksana_A [137]

Alright!
1/4 = 0.25
.25(-12x+16) 7(-x-2)
(-3x + 4)(-7x-14)
21x^2 + 14 x - 56
Do you want me to find the roots or is this enough?
You can do a lot of things with the question you asked, you need to be more specific.
