I'm not 100% positive but if my calculations are right then there is a 7.2% chance that a green bead will be drawn 25 times. I hope that helped.
Greetings.
The answer is (5,4)
Explanation:
Solving by elimination can be done by adding or subtracting of first and two equation.
Find any terms that make themselves = 0.
And that is the y-term.
Our 2y and -2y. If we add each others, we'd get 0 for y-term.
Therefore, we eliminate the y-term first.

If you are wondering how I get 2x = 10 then here's the explanation.
So we simply add/subtract both equations.
We do -x + 3x = 2x
Then +2y - 2y = 0
And 3 + 7 = 10
That's how we get 2x = 10.
Basically Add/Subtract in Vertical way.

We may get the x-value but we need to know the y-value too.
Therefore, substitute x = 5 into any given equations. I suggest you to substitute the x-value in any equations with less coefficient value.
I'd rather substitute x = 5 in -x+2y = 3.

Substitute x = 5 in -x + 2y = 3

Therefore, when x = 5, y = 4. Since you want the answer in ordered pairs then It's (5,4).
Answer: x² + 5x = 3
Step-by-step explanation:Step-by-step explanation:
The rectangle has been divided into a square and three rectangles.
The area of
a square = (x)(x) = x²
a rectangle #1 = (2)(x) = 2x
a rectangle #2 = (3)(x) = 3x
a rectangle #3 = (2)(3) = 6
The area of a large rectangle is the sum of the square area and three rectangles, and is 9 cm². Therefore we have the equation:
x² + 2x + 3x + 6 = 9 subtract 6 from both sides
x² + 5x + 6 - 6 = 9 - 6
x² + 5x = 3
Answer:
A and C are the right answers
Step-by-step explanation:
Top row only
3 out of the 12 squares are shaded in therefore 3/12 which you can simplify into 1/4
Left column only
3 out of the 6 squares are shaded in therefore 3/6 which you can simplify into 1/2
Answer:
1/2(6x-8)-2=39
.5(6x-8)-2=39
3x -4 -2 = 39
3x-6=39
3x-6+6=39+6
3x=45
3/3x=45/3
x=15
Step-by-step explanation:
1/2(6x-8)-2=39
.5(6x-8)-2=39
3x -4 -2 = 39
3x-6=39
3x-6+6=39+6
3x=45
3/3x=45/3
x=15
