we have,
14x+8+6x+12=180 {interior angle}
or, 20x+20= 180
or, 20x= 180- 20
or, x= 160/20
:. x= 8
Now,
14x+8= 14.8+8
= 112+8 =120
6x+12= 6.8+12
= 48+12 = 60

Ratio of red marbles to blue marbles is 2:3. If there are 6 red marbles, how many blue marbles are there
Answers
Answer:
6:9
Step-by-step explanation:
Lets assume the relationship between the amount of blue and red marbles are proportional. If there are 6 red marbles , then we would need need to find out how much times you multiplied 2 by to get.
6/2 is 3, which means that you multiplied the red marbles by 3 to get 6 of them.
Since the relationship between red and blue marbles is equivalent, we just need to multiply the blue marbles by 3 as well, to even it out.
3x3=9
There are 9 blue marbles if there are 6 red marbles.

Latisha’s friend Brandee forgot to make up a test and had these scores: 80%, 92%, 91%, ,75% ,89% ,84% ,0% and . 85% Homework Help ✎
Calculate Brandee’s mean. (Refer to the glossary in the eBook if you do not remember how to do this.) Does this average score really represent her abilities? Why or why not?
Brandee persuaded her teacher, Ms. Juarez, to allow her to make up the missed test. Brandee received a . Calculate her new mean.
What difference did the score make? Does this new mean represent Brandee’s ability more accurately?
Answers
Using mean and outlier concepts, it is found that:
Brandee's mean was of 74.5, which doesn't really represent her abilities, as in 7 of the 8 tests she got higher grades than this, but her mean is really affected by the outlier grade of 0%, for the test she missed.Brandee's new mean will be of 85.75, which increases her final grade by 11.25 points, and is a more accurate representation of her abilities, as there is not an outlier grade.--------------------------
The mean of a data-set is the sum of all it's values divided by the number of values.In this question, the data-set is Brandee's grades, that is: 80%, 92%, 91%, ,75% ,89% ,84% ,0% and 85%.--------------------------
There are 8 grades.Thus, the mean is:
[tex]M = \frac{80 + 92 + 91 + 75 + 89 + 84 + 0 + 85}{8} = 74.5[/tex]
Brandee's mean was of 74.5, which doesn't really represent her abilities, as in 7 of the 8 tests she got higher grades than this, but her mean is really affected by the outlier grade of 0%, for the test she missed.
--------------------------
Supposing her grade on the make up test was of 90%, the new mean will be of:[tex]M = \frac{80 + 92 + 91 + 75 + 89 + 84 + 90 + 85}{8} = 85.75[/tex]
Brandee's new mean will be of 85.75, which increases her final grade by 11.25 points, and is a more accurate representation of her abilities, as there is not an outlier grade.

Members of a baseball team raised $1781.25 to go to a tournament. They rented a bus for $1063.50 and budgeted $65.25 per player for meals. Write and solve an equation which can be used to determine x x, the number of players the team can bring to the tournament.
Answers
Answer:x=11
65.25x + 1063.50= 1781.25
To solve this equation, subtract the rental cost of the bus to get $717.75.
Now the equation should be 65.25x= 717.75
Divide both sides by 65.25, and you should get that x = 11. That’s your finally answer!

The length of a rectangle is 10 cm more than 3 times the width. The perimeter is 180. What are the dimensions?
Answers
Length = 10 + 3w
Perimeter = 2l + 2w

20 + 6w + 2w = 180
20 + 8w = 180
8w = 180-20
8w= 160
w= 20
Dimensions:

8×2+5^2-y=2(y+1)+6
Answers
Answer:
y = 11
Step-by-step explanation:
8 × 2 + 5²- y = 2(y + 1) + 6
8 × 2 + 5²- y = 2y + 2 + 6
8 × 2 + 25 - y = 2y + 2 + 6
16 + 25 - y = 2y + 2 + 6
41 - y = 2y + 8
41 (- y + y) = (2y + y) + 8
41 = 3y + 8
41 - 8 = 3y (+ 8 - 8)
33 = 3y
33/3 = 3y/3
y = 11

can you figure out what 2x° equals and (90-x)°
Answers
Answer:
x = 30
Step-by-step explanation:
The given angles are alternate which means their measurement is equal to each other so we can use the following equation to determine the value of x
2x = 90-x send x to the other side of the equation
2x + x = 90
3x = 90 divide both sides by 3
x = 30
