Please Help ME!!!

1. If ST=17 and RT=47​, find RS. Use the number line below.
<-R---------------------------------------------------------------------------S---------------------------------T->
2.On a number​ line, suppose point E has a coordinate of 3 ​, and EG=6. What are the possible coordinates of point​ G?
3.Find the length of the segment _AB_.
<-12-------'-11'-'-10'-9'-9'-'-8'-'-7'-'-6'-'-5'-'-4'-'-3'-'-2'-'-1'-0-'1'-'2'-'3'-'4'-'5'-'6'-'7'-'8'-'9'-'10'-'11'-'12'
A is -2 and b is 4 the length is?
Please help me!

Explanation:

1

RS = RT - ST

RS = 47 - 17

RS = 30 cm

2.

Coordinate = 3 ± 6

If 3 + 6 = 9

If 3 - 6 = -3

3

AB = 4 - (-2)

AB = 6

Answer:

#1

Segment addition:

  • RS + ST = RT
  • RS + 17 = 47
  • RS = 47 - 17
  • RS = 30 units

#2

There are two possibilities:

  • G is to the left of E. Then G = 3 - 6 = -3
  • G is to the right of E. Then G = 3 + 6 = 9

So possible coordinates of G are -3 or 9

#3

The length of the segment is the absolute value of the difference of the end point coordinates.

  • AB = 4 - (-2) = 4 + 2 = 6 units
