Final answer:
To calculate the value of F when P equals three, substitute 3 into the equation F = P + 3, giving F = 3 + 3, which simplifies to F = 6.
Step-by-step explanation:
The student's question involves using a given algebraic equation to find the value of one variable when another variable's value is known. The equation provided is F equals P + 3. To find the value of F when P equals three, substitute the given value of P into the equation:
F = P + 3
F = 3 + 3
By performing the addition, we get:
F = 6
Therefore, the value of F when P equals three is 6.
