13. 0

14. 4

15. 0

*12. 10

Step-by-step explanation:

Given values of each variable:

n = 2

q = -1.5

r = -3

v = -8

w = 4.5

x = 4

Since all variables' values are given, the process of simplification is simple:

13:

|-2x + 5n| + (n-x) First, plug in all known values.

|-2(4) + 5(2)| + (2 - 4) Simplify the expressions in each of the parentheses.

|-8 + 10| + (-2) Add -- Addition of a negative is subtraction.

|2| - 2 The absolute value of 2 is 2.

2 - 2 Subtract.

14:

4w - |2r + v| First, plug in all known values.

4(4.5) - |2(-3) + (-8)| Simplify the expressions in each of the parentheses.

18 - |-6 - 8| Subtract the values in the parentheses.

18 - |-14| The absolute value of -14 is 14.

18 - 14 Subtract.

15:

3|w - n| - 5|q - r| First, distribute the 3 and 5.

|3w - 3n| - |5q - 5r| Plug in all known values.

|3(4.5) - 3(2)| - |5(-1.5) - 5(-3)| Distribute--Subtraction of a negative is addition.

|13.5 - 6| - |-7.5 + 15| Simplify the expressions in each of the parentheses.

|7.5| - |7.5| The absolute value of 7.5 is 7.5.

7.5 - 7.5 Subtract.

8. - 11. are correct. However, 12. is 10 because you need to distribute before simplifying what's in the parentheses.

Answer from: Quest

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

= pi 5^2

= 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360 60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
