Answer:
4
Step-by-step explanation:
plug in 2 for the a variables and you get 4 as the answer.
You're starting at 400. Each time you're cutting in half.
So the common ratio is 1/2 which means the equation is
which is in the geometric sequence format. So the answer is choice D
Answer:
Step-by-step explanation:-12x=2
X=-12/2
X=-6
49 - 2/3 <em>x</em> = 32 - 1/6 <em>x</em>
Move the constant terms to one side and the terms containing <em>x</em> to the other:
49 - 32 = 2/3 <em>x</em> - 1/6 <em>x</em>
Simplify the left side, and pull out the common factor of <em>x</em> on the right side:
17 = (2/3 - 1/6) <em>x</em>
Write the fractions in terms of a common denominator. In this case, you would take
2/3 = 4/6
so that
(2/3 - 1/6) <em>x</em> = (4/6 - 1/6) <em>x</em> = 3/6 <em>x</em> = 1/2 <em>x</em>
Then the equation is
17 = 1/2 <em>x</em>
Multiply both sides by 2:
2 × 17 = 2 × 1/2 <em>x</em>
34 = <em>x</em>
Answer: okay so the measure of angle 1 is 72 degrees. Angle 2 is 108 degrees. Angle 3 is 72 degrees. And angle 4 is 108 degrees.
Step-by-step explanation:
I know this because to find angle 1 we are going to subtract 180 degrees from 108 degrees. A straight line like this is 180 degrees. Angle 2 is going to be exactly 108 and angle 3 is also going to be 72 degrees. Angle 4 is 108 degrees because 180-72 is 108
