The median is the number in the middle of a sorted list.
So we need to arrange the given numbers, $699, $826, $839,
$880, $965, $1,087.
Since the givenhas 6 numbers, finding the median will be
the average of the two numbers in the middle.
$839 + $880 = 1719 then divide this by 2 = 859.5
So there are 3 numbers that are below the median and these
are $699, $826, and $839.
2 angles are Complementary, if the sum of their measures = 90°.
Let the 2 angles be A and B, and let their measures be m(A)=a, m(B)=b.
Let A be the larger angle.
"the larger angle is six more than three times the smaller angle."
can be 'translated' into algebra as: a = 6 + 3b
Also, since A and B are complementary, we have a+b=90°.
substitute a=6+3b in the second equation:
a+b=90°
(6°+3b+b)=90°
4b=90°-6°
b=84°/4=21°
Then, a = 90°-21°=69°
Answer: a= 69°, b=21°
In this problem, you combine the like terms...
4a - 3b + 7a
4a and 7a are like terms so you add them together.
4a + 7a = 11a
So, the answer is: 11a - 3b
