The answer should be 299/52=almost 6 hours.
For this case we define the following variable:
- <em>x: number of stamps
</em>
We now write the equation that models the problem:

From here, we clear the value of x.
We have then:

Answer:
The number of stamps he has is:

Jacob=5 5/6 ft
Linda=5 1/4
So to find out the difference, we first have to make the fractions equivalent.
5/6x2/3=10/12
1/4x3/3=3/12
Now we subtract.
5 10/12-5 3/12
=7/12
Jacob is 7/12 ft taller than Linda.
Obtuse, it does not fit Pythagoreans for a right triangle, two sides are not equal to be isosceles
