Final answer:
To make x the subject of the formula x/5t = q + 1, isolate x by multiplying both sides by 5t and distributing q + 1. The correct answer is x = 5tq + 5t.The correct option is A.
Step-by-step explanation:
To make x the subject of the formula x/5t = q + 1, we need to isolate x.
Step 1: Multiply both sides of the equation by 5t to eliminate the fraction: x = (q + 1) * 5t.
Step 2: Distribute q + 1: x = 5tq + 5t.
So, the correct answer is x = 5tq + 5t.
