A bag contains 9 marbles: 5 are green, 2 are red, and 2 are blue.

EleoNora [17]

Answer: 5/9 x 2/8. The probability that the first marble is green and the second is red is 13.8%. In fraction form, the answer is 5/9 x 2/8 because the two outcomes must be multiplied. I really hope that helps!

If 8/9 of a number is 328, find the number

Gre4nikov [31]

Answer: the number is 369

Step-by-step explanation:

Let the missing number be y

8/9 × y = 328

8/9y = 328

Divide both sides by 8/9

y = 328 ÷ 8/9

y = 328 × 9/8 (multiply the two numerators: 328 x 9= 2952

Multiply the denominator by 1: 8 x 1= 8

Therefore y = 2952/8

y = 369

I hope this helps.

Write an equation in slope-intercept form that contains the points (2, 8) and (4, 9).

ololo11 [35]

Given two points, the equation of the line in slope form can be obtained using this equation

$\frac{y_2-y_1}{x_2-x_1}\text{ = }\frac{y_{}-y_1}{x_{}-x_1}$

Now we can name the points

x1 = 2, y1 = 8

x2 = 4 , y2 =9

These coordinates can then be substituted into the equation

$\frac{9-8}{4-2}\text{ =}\frac{y\text{ - 8}}{x\text{ - 2}}$

$\begin{gathered} \frac{1}{2}\text{ = }\frac{y\text{ - 8}}{x\text{ - 2}} \\ \\ x-2\text{ = 2 (y - 8)} \\ \\ x\text{ - 2 = 2y - 16} \end{gathered}$

x - 2 + 16 = 2y

2y = x - 2 +16

2y = x + 14

Divide both sides by 2

y = x/2 + 14/2

$y\text{ = }\frac{x}{2}\text{ + 7}$

This is the equation in slope-intercept form

where the slope = 1/2
