Problem 7

(45 pages)/(90 min) = 1/2 page per min, i.e. 1 page per 2 minutes

(60 pages)(120 min) = 1/2 page per min

Both lead to the same result, so yes they are proportional.

Their reading speed is identical.

Factor 1/3 out of 1/3p-2/3 please answer this! Easy 20 points!

Tju [1.3M]

Answer:

$\frac{1}{3} (\frac{1}{p} - 2)$

Step-by-step explanation:

Given the equation = $\frac{1}{3p} - \frac{2}{3}$

Required: To factor out 1/3;

$\frac{1}{3p} - \frac{2}{3}$

1/3 is common to both sides;

So, 1/3 is a common factor

$\frac{1}{3} (\frac{1}{p} - 2)$

To solve for the value of p;

$\frac{1}{3} (\frac{1}{p} - 2)$ = 0

$\frac{1}{p} - 2 = 0$

$\frac{1}{p} = 2$

$1 = 2p$

$p = \frac{1}{2}$
