Locating -1.5 on a number line is the same as locating 1.5 because both numbers are the same distance from zero, but in opposite directions. The numbers also have the same absolute value.
Locating -1.5 and 1.5 is different because -1.5 can be found to the left of zero (because it is a negative number) while 1.5 is found to the right of zero (because it’s a positive number).
The first number is 20
The second is 40
The third is 70
the first number = a
The second number = 2a
The third number = 3 1/2a
6 1/2a = 130
a = 20
Hope this helps!
