Question

solve for p.
\\(\frac{p - 3.1}{6.7} = \frac{4.5}{5}\\)
\\(\bigcirc\\ p = -9.47\\)
\\(\bigcirc\\ p = 2.93\\)
\\(\bigcirc\\ p = 9.13\\)
\\(\bigcirc\\ p = 21.53\\)

Explanation:

Step1: Cross-multiply to eliminate fractions

$$(p-3.1) \times 5 = 4.5 \times 6.7$$
$$5(p-3.1) = 30.15$$

Step2: Divide both sides by 5

$$p-3.1 = \frac{30.15}{5}$$
$$p-3.1 = 6.03$$

Step3: Add 3.1 to both sides

$$p = 6.03 + 3.1$$
$$p = 9.13$$

Answer:

p = 9.13
