Step-by-step explanation:
supplentary means they add to 180
so you can make the formula 180 = 10x + 80
then solve for x
Answer:
x = 10
Step-by-step explanation:
Supplementary angles add up to equal 180°
Thus, 10x + 80 = 180
Now that we have identified the equation we solve for x
10x + 80 = 180
step 1 subtract 80 from each side
80 - 80 cancels out
180 - 80 = 100
we now have 100 = 10x
step 2 divide each side by 10
100 / 10 = 10
10x / 10 = x
we're left with x = 10

-5 1/4 - (-7 1/2)
A) -12 3/4
B) 2 1/4
C) -2 1/4
D)2 3/4
Answer:
2 1/4
Step-by-step explanation:
-5 1/4 - (-7 1/2)
Subtracting a negative is like adding
-5 1/4 + (7 1/2)
Get a common denominator
-5 1/4 + (7 1/2 *2/2)
-5 1/4 + (7 2/4)
Since the signs are different, we subtract the smaller from the larger and take the sign of the larger
7 2/4 - 5 1/4

Which of the following is likely to have the
greatest variability?
A. The cost of a piece of candy from a vending
machine
B. The height of all the students at West Middle
School
The age of all the students in the sixth grade
D. The number of days in a month
Answer:
B. The height of all the students at West Middle school
Step-by-step explanation:
The greatest variability is a large spectrum of possibilities.
The costs of candy from a vending machine are all going to be about the same price because they are all candy, so that doesn't vary much.
The age of all the students in the sixth grade is going to be about the same because they are in the same grade.
The number of days in a month is usually 31 or 30, so that also does not vary much.
This means that it has to be the height of all the students at West Middle school because it is a middle school so there are 3 different grades each having many students. This means that it will have the greatest variability.
Im on a girls basketball team , 3 are in sixth grade , 5 are in seventh grade , and 6 are in eighth grade . so which is the ratio of seventh graders to eighth graders on the team ?

Answer:
Option 1
Step-by-step explanation:
In the first one, the first number is lower than -2, the second is between -1 and 0, and 1+1/6 is of course bigger than 0 and smaller than 1+5/6, so it's the right answer.
The second one is the first one reversed, so it's ordered from greatest to lowest.
The third one has a negative number on both ends, but positives in the middle, so it cannot be ordered lowest to greatest. Same with the last one.
