8 diamands = red cards
6 spades = black cards
It means that total number of red cards is 11, total number of black cards is 6 and total amount of cards is 17 (in this deck)
so probabilty of choosing red card from this deck will be 11 to 17 (red cards to all cards in this deck)
or you can write it down as percentage
Your answer then is 67.71% or probabilty of chosing red card is like 11 to 17

Right off the bat, we can see that 1260 is an even number, so we will start by dividing by 2, since all even numbers are divisible by 2
1260 / 2 = 630
Again, the number is obviously divisible by 2, so we will do it again
630 / 2 = 315
315 is not divisible by 2, so let us check if it is divisible by 3.
A proven way to do this is to add the individual numbers in the bigger number, and if that number is divisible by 3, then the bigger number is also divisible by 3.
3 + 1 + 5 = 9
9 is divisible by 3, so we know that 315 is also divisible by 3.
315 / 3 = 105
If any number (except 0) ends with a 5 or a 0, then it is divisible by 5.
105 / 5 = 21
21 is again divisible by 3
21 / 3 = 7
So there are our prime factor numbers.
The prime factorization of 1260 is as follows:
2 * 2 * 3 * 3 * 5 * 7
Hope that helped =)

7 . X + 2y = 4 (move x beside 4, since it's positive it will be negative)
2y = 4 - X (divide terms to 2)
| 2y ÷ 2 = y | 4 ÷ 2 = 2 | -X ÷ 2 = -1/2 (There's always an imaginary 1 beside x, only just x).
y = 2 - 1/2x (rearrange terms)
y = -1/2x + 2
9. -2x + 3y = -6 (move -2x beside -6, since it's negative it will turn into a positive)
3y = -6 + 2x (divide by 3)
y = -2 + 2/3x (rearrange)
y = 2/3x -2
11. 5x - 2y = 14
-2y = 14 - 5x (-2 ÷ -5x is 5/2x, but since numerator and denominator are negative, fraction turns positive)
y = -7 + 5/2x
y= 5/2x - 7
13. 4x + 3y = 12
3y = 12- 4x
y = 4 -4/3x
y = -4/3x + 4
15. x + 3y = -3
3y = -3 -x
y = -1 -1/3x
y -1/3x - 1
There you go!
Just remember those steps and you should be fine :)

Answer:
x = -2 if its 4(3x + 5) = -4
OR
x = 4/3 if its 4(3x - 5) = -4
Step-by-step explanation:
Your missing an plus or minus sign.
4(3x + 5) = -4 / multiply contents of parentheses by 4
12x + 20 = -4 / subtract 20 from both sides
12x = -24 / divide both sides by 12
x = -2
OR
4(3x - 5) = -4 / multiply contents of parentheses by 4
12x - 20 = -4 / add 20 to both sides
12x = 16 / divide both sides by 12
x = 16/12 / simplify
x = 4/3
Answer: -2
Step-by-step explanation:
To solve the equation 4(3x + 5) = -4, we need to follow these steps:
Step 1: Distribute the 4 to the terms inside the parentheses.
This gives us 12x + 20 = -4.
Step 2: Subtract 20 from both sides of the equation to isolate the variable term.
We get 12x = -4 - 20, which simplifies to 12x = -24.
Step 3: Divide both sides of the equation by 12 to solve for x.
Dividing both sides by 12 gives us x = -24/12, which simplifies to x = -2.
So, the solution to the equation 4(3x + 5) = -4 is x = -2.
