Total number of marbles: 12+9 = 21
Possibility of withdrwaing a white marble = 9/21 = 3/7 = 3:7

Well if you take the two numbers and divide them, 9/12 you get 3/4 i would probably say B. 3:4

Hi does anyone know the answer?

Artemon [7]

Answer:

The correct equation is actually: y=10x+10.

Jaiden calculated the slope of the line incorrectly, as the y-axis increases by 10, not 2. The correct slope of the line is 20/2, which is equal to 10.

Hope this helps!

Evaluate the expression. ( – 5+ – 9)× – 3÷ – 2

Ronch [10]

Answer:

$-21$

Step-by-step explanation:

$( - 5+ - 9) \times - 3 \div - 2$

Solve the brackets first.

$( - 14) \times - 3 \div - 2$

Division comes next.

$( - 14) \times - 3/-2$

Cancel the negative signs.

$- 14 \times 3/2$

Multiply the terms.

$-42/2$

$=-21$
