1/3+2/5+4/3+3/5=8/3
Steps
A double negative makes a positive.
So, change all double negatives to positives (to simplify it)
1/3 + 2/5 + 1+1/3 + 3/5
What's the least common denominator here?
Yes, it is 15!
Change the fractions to that denominator
5/15 + 6/15 + 1+5/15 + 9/15
change 1+5/15 to 20/15, then add the fractions
Result: 40/15
Divide numerator and denominator both by the greatest common factor:5
8/3
First you get "y" by itself. To do so you divide 2 on both sides.
y = 3/2x + 5
To write an equation of a line that is PARALLEL to this equation, the slopes have to be the SAME. So the slope is 3/2.
You then use the equation:
y = mx + b
SInce you know "m" you plug it in.
y = 3/2x + b
Now you need to find b. To do so you plug in the point (2, -5) into this equation.
-5 = 3/2(2) + b
-5 = 3 + b
-8 = b
Finally you plug in b and you get your new equation.
y = 3/2x - 8
To find the length of the missing side x, use Tan trigonometric formula
Tan: 
Tan 21 = 
Tan 21 × 
= ×
x=27.4
X= 27.4 ft

Answer is D, 16. There is a rule about circles regarding this. When there are chords in the circle of equal measure, the distance from the center of the circle to the midpoint of the chord is equal.
Answer:
2
Step-by-step explanation:
step 1) simplify
11/14-x/4=2/7
-x/4=2/7-11/14
-1/4x=-1/2
divide both sides by -1/4
x=2
