<span> For this case we have the following system of equations:
</span>
<span>
Where,
x: time in hours walking
Y: time in hours on the bus
We solve the system of equations.
Rewriting the system we have:
</span>
<span> Adding both equations we have:
</span>
<span> Clearing x we have:

Then, the number of Yochanan road miles is:
</span>
<span>
Answer: Yochanan walked about: 5 miles</span>
Because the square has similar lengths, the equation would be
(7x-2)(7x-2)
We can use FOIL to solve this:
The area is 49x^2 - 28x + 4 in^2.
Answer:
The solutions to equation 1 are x = 3, −1.5, and equation 2 has no solution.
Step-by-step explanation:
Rearranging the two equations, you get ...
- |4x -3| = 9 . . . . . has two solutions
- |2x +3| = -5 . . . . has no solutions (an absolute value cannot be negative)
The above-listed answer is the only one that matches these solution counts.
_____
Testing the above values of x reveals they are, indeed, solutions to Equation 1.
This is an application of the pythagorean theorem.
c^2 = h^2 + b^2
c = 190
b = 102.5
h = ???
190^2 = h^2 + 102.5^2
16100 = h^2 + 10506.25
36100 - 10506.25 = h^2
25593.75 = h^2
sqrt(25593.75) = h
159.98 = h
