Answer:

8. x=18  9. x=33   10. x=65  11. x=19  12. x=59

Step-by-step explanation:

8.  The angles are essentially vertical so they have to be equal to each other.

42=2x+6   subtract 6 from both sides  36=2x   x=18

9.  These angles are supplementary and equal 180 when added together.

98+(3x-17)=180  subtract 98 and add 17 to both sides  3x=99  x=33

10.  Angles are essentially vertical so they are equal to each other.

2x+2=3x-63  add 63 to both sides subtract 2x from both sides  65=1x

11.  Angles are supplementary so they equal 180 when added together.

112+(4x-8)=180 subtract 112 and add 8 to both sides   4x=76   x=19

12.  Angles are vertical so they are equal to each other.

(3x-33)=(2x+26)  add 33 to both sides and subtract 2x   59=1x

Half a number increased by 4 is the same as six less than that number

Answers

Answer:

the number is 20

Step-by-step explanation:

Denote the number as "x",

write out the problem:

(1/2(x)) + 4 = x - 6

inverse operations

(1/2(x)) + 4 = x - 6

           +6        +6

(1/2(x)) + 10 = x

-(1/2(x))           -(1/2(x))

10 = ((1/2)x)

*2       *2

20 = x
