Question

If rs = 15 and rt = 18 then st =

Answer 1

To solve for st, we can subtract the equations rs - rt.

Step-by-step explanation:

The question is asking to find the value of st given that rs = 15 and rt = 18.

Given that rs = 15, we know that r + s = 15.

Given that rt = 18, we know that r + t = 18.

Subtracting the second equation from the first equation, we get:

(r + s) - (r + t) = 15 - 18

s - t = -3

Therefore, st = -3.

Answer 2

30, since both have r, then the common factor can be 3. In other words, r can be 3 for both equations. This means that s=5, and t=6. So 5*6=30
