Answer:
C) 14
Step-by-step explanation:
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
First, add 6 to both sides:
3x - 6 (+6) = 36 (+6)
3x = 36 + 6
3x = 42
Next, divide 3 from both sides:
(3x)/3 = (42)/3
x = 42/3
x = 14
c) 14 is your answer.

Answer:

Step-by-step explanation:
Circle F and J are congruent.

Given that: m∠DFE = 80°
DFE is the central angle of the circle F.
The measure of arc GH is equal to the central angle of Circle J.
Since both circles are congruent

The measure of arc GH is 80 degrees.
Since 1 kiloliter = 100 centiliter, so
7.7 kL (100 cL/1 kL) = 700 cL
Hope this helps.
