1 answer:
The unit rate you're trying to find is pages per day(or p/d), so the equation needs to have both a unit for pages and for days.
The equation we have is:
If they read 5,249 <em>pages</em>, then we can include the unit for pages in the equation.
Since we also know that <em>d</em> is the number of days it took, you can replace <em>d</em> with days.
The equation becomes:
Now that we have one variable, we can solve for <em>p/d</em>:
Thus it took them 181 days to read it all.
If Johnny read 5,249 pages over 181 days and the unit rate is pages per day(p/d), then the equation for finding <em>p/d</em> is:
Johnny read 29 pages per day.

The given question is illustrated with the attached image.
To do this, we simply calculate the measure of angle a using:
Take arctan of both sides
Answer:
begin{aligned}
& x = \frac{D_x}{D} = \frac{-616}{-154} = 4 \\
& y = \frac{D_y}{D} = \frac{ 616}{-154} = -4 \\
& z = \frac{D_z}{D} = \frac{-770}{-154} = 5
