Question 15 of 43

Andrews [41]

Answer:

Option A

Step-by-step explanation:

$\frac{12}{25} \times \frac{11}{24} \times \frac{10}{23} \times \frac{9}{22}$

we start with 12 red marbles out of 25 marbles, that's the probability for the first.

in the second step we have one red marble less, wich also means one marble less overall

and so on

$\frac{12 \times 11 \times 10 \times 9}{25 \times 24 \times 23 \times 22}$

$= \frac{11880}{303600}$

can be reduced by 1320 (step by step) to

$\frac{9}{230}$

2x+3y = 15<br> x-3y=3<br> Solve

Arada [10]

By process of elimination. 3y and -3y get eliminated. Giving you

3x=18

Divide by 3 on each side

Giving you x=6

Plugging it into equation 2 you get

(6)-3y=3

Taking out the parenthesis you have

6-3y=3

Subtract by 6 on each side giving you

-3y=-3

Divide by -3 on each side giving you

y=1

So the answer for this equation is x=6 and y=1 or the ordered pair (6,1)
