3(x - 6) - 4(x + 3) = 3x - 18 - 4x - 12 = -x - 30

Answer:

-x-30

Step-by-step explanation:

first you need to distribute:

3(x)+3(-6) -4(x)+ (-4)(3)

Then you multiply:

3x+(-18)-4x+(-7)

then you combine like terms:

3x-4x= -1x

-18+(-7)= -25

simplified:

-1x-30

Answer:

See below ~

Step-by-step explanation:

P (6th grader)

No. of 6th graders / Total students
6 / 6 + 7 + 8
6/21
2/7

P (6th grader after)

No. of 6th graders - 1 / Total students - 1
6 - 1 / 21 - 1
5/20
1/4

Question 1 : P (Both 6th graders)

P = P (6th grader) × P (6th grader after)
P = 2/7 x 1/4 = 2/28 = 1/14

Question 2 : P' (Both 6th graders)

P' = 1 - P
P' = 1 - 1/14
P' = 13/14

1) m∠1 = 360°/8 = 45° . . . . . a regular octagon is 8-way rotationally symmetrical, so each sector is 1/8 of a circle.

2) m∠2 = (180° -45°)/2 = 67.5° . . . . . . the angles of a triangle add to 180°. The base angles of an isosceles triangle are equal.
