Length of the mid-segment = (long base + short base) / 219 = (27 + short base) / 219 - (27 / 2) = short base / 2Multiplying both sides by 238 -27 = short baseshort base = 11

Answer:
green has the most marbles.
Step-by-step explanation:
red=25%
green=1/3=33%
brown=2/10=20%
blue=remainder=22%
It would be A because -2 times +6 equals -12
The value of x in the equation is - 3.
<h3>How to find the variable in an equation?</h3>
Variables are number represented by a letter in an equation.
Therefore,
-5x - 9 = 2x + 12
subtract 12 from both sides of the equation
-5x - 9 = 2x + 12
-5x - 9 - 12 = 2x + 12 - 12
-5x - 21 = 2x
add 21 to both sides of the equation
-5x - 21 = 2x
-5x - 21 + 21 = 2x + 21
-5x = 2x + 21
subtract 2x from both sides
-5x = 2x + 21
-5x - 2x = 2x -2x + 21
-7x = 21
divide both sides by -7
-7x / -7 = 21 / - 7
x = -3
