Answer:
21x
Step-by-step explanation:
In the parentheses, 3 * x is the same thing as 3x. Distribute 7 into 3x to get 21x as your final answer.
The equivalent measurement in degrees is 150°
<h3>Measurement of angle</h3>
Angles can be measured in radians or degrees.
Radians are mostly used for very small angular measurement.
Analysis:
For every π radians covered, the angular measurement is 180°
So 5/6π = 5/6 x 180 = 5 x 30 = 150°
In conclusion, the angular measurement in degrees of 5/6π is 180°.

#SPJ1
Answer:
A
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
n is an exterior angle of the triangle.
The 2 opposite interior angles are
180° - 131° = 49° and 180° - 160° = 20°, thus
n = 49° + 20° = 69° → A
Answer:
Imagine an easier version of this problem: You have a board 5 feet long that you must cut (divide, right?) into two equal parts. It is probably clear to you that you simply divide the length (5) by the number of parts you're dividing it into (2) to obtain the length of each piece (2.5 feet).
Use the same method for your problem 5 feet divided by 6 is 0.83 feet per piece.
We do not ordinarily divide feet into decimal portions, but instead into inches. Since an inch is 1/12 of a foot, you could simply say 5/6 = how many twelfths? or 5/6 = n/12 Solve this by inspection or by cross multiplying 5 times 12 equals n times 6. So n must equal 10, and your pieces of board are each 10 inches long.
Raj earned 58 and spent 42, so he saved 58-42 = 16.
Michael earned 83 and saved 20, so he spent 63, but that doesn't matter.
for Raj, 100% of his earning is 58, how much is 16 off of it as a percentage?
for Michael, 100% of his earnings is 83, how much is 20 off of it as a percentage?
and you can see clearly which percentage is higher.
