In Paige's scrapbook, she has completed 40 of the 50 pages. Each page is part of a spread, and each spread has a left and a right page. Twenty-five pages will have journaling, where she writes to explain what was happening when the pictures were taken. On a few of the pages she has also included a souvenir of some sort. One third of the pages have a thin border, one third has a thick border, and one third has a graphic border. Which is a uniform probability model for the scrapbook pages?

A. completion
B. souvenirs
C. color
D. journaling

40/50

25 pages have journalism - 25 pages

Few pages have a sort of souvenir - 2 pages

1/3 of pages are thin - 4 pages

1/3 of pages have a thin border - 4 pages

1/3 of pages are thick - 4 pages

Well my answer would be D.Journalis.

(If I am wrong I am VERY sorry, I am a sixth grader sooo)

simplifying

5(x + -6) = 2(x + 3)

reorder the terms:

5(-6 + x) = 2(x + 3)

(-6 * 5 + x * 5) = 2(x + 3)

(-30 + 5x) = 2(x + 3)

reorder the terms:

-30 + 5x = 2(3 + x)

-30 + 5x = (3 * 2 + x * 2)

-30 + 5x = (6 + 2x)

solving

-30 + 5x = 6 + 2x

solving for variable 'x'.

move all terms containing x to the left, all other terms to the right.

add '-2x' to each side of the equation.

-30 + 5x + -2x = 6 + 2x + -2x

combine like terms: 5x + -2x = 3x

-30 + 3x = 6 + 2x + -2x

combine like terms: 2x + -2x = 0

-30 + 3x = 6 + 0

-30 + 3x = 6

add '30' to each side of the equation.

-30 + 30 + 3x = 6 + 30

combine like terms: -30 + 30 = 0

0 + 3x = 6 + 30

3x = 6 + 30

combine like terms: 6 + 30 = 36

3x = 36

divide each side by '3'.

x = 12

simplifying

x = 12

this should .
