Answer:
x = -1
Step-by-step explanation:
Note that all terms have 13 in the denominator. In such a case as this, you can remove the denominators (only when each and EVERY one of them are the same is this possible).
4x/13 + 3/13 = -1/13 ⇒ 4x + 3 = -1
Simplify. Isolate the variable, x. Do the opposite of PEMDAS. Note the equal sign, what you do to one side, you do to the other.
Subtract 3 from both sides.
4x + 3 = -1
4x + 3 (-3) = -1 (-3)
4x = -1 - 3
4x = -4
Divide 4 from both sides.
(4x)/4 = (-4)/4
x = (-4)/4
x = -1
-1 is your answer for x.

Answer:
11.2
Step-by-step explanation:
x is the length of a radius of the circle, all radii have the same length.
the chord of length 20 is perpendicular to the segment of length 5, so the segment bisects the chord , so half of the chord is length 10.
The segment of length 10 is one leg of a right triangle while the segment of length 5 is the other leg. The hypotenuse is also a radius of the circle.
The length of the hypotenuse can be found by they Pythagorean Theorem, a^2 + b^2 = c^2, so
5^2 + 10^2 = c^2 or
25 + 100 = c^2 or
c^2 = 125 or
c = = ≈ 11.2
so if one radius is approximately 11.2, then all radii (including the one of length x) are 11.2
It takes 8 hours to drive to Joliet, and that's 6 hours more than half the time it takes to drive to Davenport. So, I did 8-6 which equals 2. So 2 hours is half the time it takes to get to Davenport, which means it takes 4 hours to get to Davenport.
