Question

mark for review
a = 7 = 25p + k
the given equation relates the positive numbers a, p, and k. which equation correctly expresses a in terms of p and k?
(a) a = 25p + k + 7
(b) a = 25p + k - 7
(c) a = 7(25p + k)
(d) a = \frac{25p + k}{7}

Explanation:

Step1: Isolate \(c\) by adding 7

Start with the given equation:
\(c - 7 = 25p + k\)
Add 7 to both sides:
\(c - 7 + 7 = 25p + k + 7\)

Step2: Simplify the equation

Cancel out \(-7\) and \(+7\) on the left:
\(c = 25p + k + 7\)

Answer:

A. \(c = 25p + k + 7\)
