There is a 1/3 chance that a red marble would be chosen.

To find out you put add up the marbles, so they will make 12 marbles.

Since there are 4 red you put 4/12.

4/12 simplified is 1/3.

So the chance of a red marble being picked is 1/3.

Your question is missing the figure, so the figure for your question is attached below:

Answer:

shade 2 strips out of 4 to get fraction strip equivalent to Mandy's fraction strip

Step-by-step explanation:

As Mandy shaded the 3 trips out of the total six strips. It shows the fraction of $\frac{3}{6}$

and $\frac{3}{6}=\frac{1}{2}$

To shade the given fraction strip so that it represents a fraction that is equivalent to Mandy's fraction strip, we should shade 2 stripes out of 4 that is equivalent to $\frac{1}{2}$

i.e. $\frac{2}{4}=\frac{1}{2}$

My Fraction Strip is equivalent to Mandy's Fraction Strip because both are equal to $\frac{1}{2}$

3y - 5z = -23

leonid [27]

Starting off, we can multiply the third equation by 2 and add it to the third to get rid of both the x and y variables. Next, we get z=1. Plugging that into 3y-5z=-23, we get 3y-5=-23. Adding 5 to both sides, we get 3y=-18. After that, we can divide both sides by 3 to get y=-6. Plugging that into -2x-y-z=-3, we get -2x+6-1=-3=-2x+5. Subtracting 5x from both sides, we get -2x=-8. After that, we can divide both sides by -2 to get x=4.

Find the slope of 9x=3y+5

qaws [65]

<u>9x</u> = <u>3y + 5</u>
9 9
x = 1/3y + 5/9
x - 5/9 = 1/3y + 5/9 - 5/9
x - 5/9 = 1/3y
3(x - 5/9) = 1/3y · 3
3x - 1 2/3 = y
y = 3x - 1 2/3
