Answer:
Step-by-step explanation:
Split the second term (5x) into two terms. Multiply the coefficient of the first term (2) by the constant term (3):
Find which two numbers add up to 5 and multiply into 6:
Split 5x as the sum of 3x and 2x:
Now factor out a common term for the first 2 terms:
And do the same for the last 2 terms:
Re-insert:
Factor out the common term 2x+3 and insert the values in front of the parentheses (x and 1):
Separate the parentheses and equal them to 0. Solve for x:
and
The "mean" of a group of numbers is also called their "average".
To calculate the mean, add up all the numbers, then
divide the sum by the number of items on the list.
Step #1: Addum up: 3+7+2+9+4+7+3+7+5+2 = 49
Step #2: Count the number of items on the list: I count 10 .
Step #3: Divide the sum by the number of items on the list.
49 / 10 = 4.9
The mean (average) of the numbers on that list is 4.9 .
Answer:
∠1 and∠3 = Supplementary Angles
∠4and∠5 = Complementary Angles
∠5and∠1 = Adjacent Angles
∠2and∠3 = Supplementary Angles
97 Rounded to the nearest tenth would be 100
