the number line shows the locations of points p q r and s

The points with a distance of 5 units between them are:

-5p and 0
-5p and 5
-4 and -3q
-3q and -2r
1 and 2s

p and s q and r q and s or r and s

Apologies for the confusion. The points with a distance of 5 units between them are:

-5p and 0
0 and 5
-3q and 2s

points p and q are plotted on the number line

-8p -6 -4 -2 0 2 4 6q 8
what expresion represents the discance between points p and q

The expression representing the distance between points p and q can be calculated by subtracting the value of p from q. Therefore, the expression would be:

q - p

last year teds salary was 42000 he donated 1/25 of last years salary to charity. how much did ted earn last year after his donation?

To find out how much Ted earned last year after his donation, we need to subtract the amount he donated from his salary.

The amount he donated is given as 1/25 of his salary, which can be calculated as:
42000 * (1/25)

Simplifying this expression, we get:
1680

Therefore, Ted earned 4200 - 1680 = 40320 last year after his donation.
