Step-by-step explanation: Theirs your help!
There are 5 little lines between 0 and -1, so each line represents 1/5.
B is located 3 lines to the left of -1, so it would be located at - 1 3/5.
Am absolute value is a positive number so - 1 3/5 would become 1 3/5.

Answer:
Step-by-step explanation:
If we let x and y represent the costs of a lamp and end table, respectively, the two purchases can be written as ...
3x +2y = 520
2x -y = 20
__
These equations can be solved many ways. If we use "elimination", we can add twice the second equation to the first to eliminate y:
(3x +2y) +2(2x -y) = (520) +2(20)
7x = 560 . . . . simplify
x = 80 . . . . . . divide by 7
y = 2x -20 = 2(80) -20 = 140
The cost of a lamp is $80; the cost of an end table is $140.
