This could be wrong because I'm going into the fifth grade but wouldn't it just be (7,-3)?
Given
x^5*k=a .................(1)
x^2*k=b .................(2)
We need to find x^3.
Solution:
On inspection, we note that (1)/(2) gives x^3 on the left hand side, but the division is valid on conditions that x ≠ 0 and k ≠ 0.
So we conclude:
(1) / (2)

<span>At 12:20, Dori has completed 1000 steps.
Malory catches up to Dori at a rate of 40 steps each minute.
The number of minutes required for Malory to catch up is:
1000 steps / (40 steps/minutes) which is 25 minutes
Malory's steps will catch up to Dori's steps at 12:45 pm</span>
