C (180 = 80 + 45 + x)
Step-by-step explanation:
When you subtract 80 and 45 from both sides, you would result in x. 180 is the sum of all triangle's interior angles.

please help. are they Parallel, perpendicular or neither
Answers
Answer:
Neither
Step-by-step explanation:
Parallel lines don't intersect
Answer:
Neither parallel or perpendicular.
Step-by-step explanation:
For AB A(-1,-4) and B(2, 11)
x1,y1 x2,y2
Gradient = (y2 - y1)/(x2 - x1)
= (11 - (-4))/(2 - (-1))
= 15/3 = 5.
For CD C(1 , 1) and D(4 , 10)
x1, y1 x2, y2
Gradient = (y2 - y1)/(x2 - x1)
= (10 - 1)/(4 - 1)
= 9/3 = 3
from the above they are neither parallel or perpendicular.

Step-by-step explanation:
4x3=12
3x3=9
12/9
Answer:
? = 9
Step-by-step explanation:
When doing a problem like this, you need to know that you are going to multiply a fraction equal to 1. (x/x)
Ask yourself: what times 4 equals 12? 3. So we know our fraction equal to 1 is 3/3
What is 3 times 3? 9. So our complete fraction is 12/9
To check: reduce the fraction:
12/9 divided by 3 is 4/3

The upper-left coordinates on a rectangle are (-1,4) and the upper-right coordinates are (3,4).The rectangle has a perimeter of 24 units Draw the answer on the coordinate planes
Answers
Answer:
The answer is below
Step-by-step explanation:
Perimeter of a rectangle = 2(length + breadth)
24 = 2(length + breadth)
length + breadth = 12
The distance between the points of the rectangle (-1, 4) and (3,4) is given as:
[tex]Distance=\sqrt{(x_2-x_1)^2+(y_2+y_1)^2}\\ \\Distance=\sqrt{(3-(-1))^2+(4-4)^2}=4\ units[/tex]
The breadth = 4 units
Length + 4 = 12
Length = 8 units
The lower left x coordinate would be the same as the upper left x coordinate, let us assume that the lower left y coordinate = a
Hence lower left coordinate = (-1, -a). The distance between (-1,4) and (-1, -a) is the length = 6 units
[tex]6=\sqrt{(-1-(-1))^2+(-a-4)^2}\\ \\a=-10[/tex]
lower left coordinate = (-1, 10)
The lower right x coordinate would be the same as the upper right x coordinate, let us assume that the lower right y coordinate = -b
Hence lower right coordinate = (3, -b). The distance between (3, 4) and (3, -b) is the length = 6 units
[tex]6=\sqrt{(3-3)^2+(-b-4)^2}\\ \\b=-10[/tex]
lower right coordinate = (3, -10)

Explanation:
The length of segment MN is the same as the distance from M to N
Count out the spaces from M to N to see that there are 5 spaces, so that's why choice A is the answer.
-------------
Or you can break it down like this:
There are 3 spaces from -3 to 0There are 2 spaces from 0 to 2So we have 3+2 = 5 spaces total between M and N.
-------------
A more formal approach:
Let M = -3 and N = 2
Now subtract and apply absolute value.
|M - N| = |-3-2| = |-5| = 5
or
|N - M| = |2-(-3)| = |2+3| = |5| = 5
Either way, we get a distance of 5 units.
Absolute value is used to ensure that the result is never negative.

Charlie paid $39.25 for a cookbook he purchased from a book club. This was a saving of $3.19 off the regular price. What percent discount did the book club give Henry?
Answers
Answer:
The book club gave Henry a 8.13% discount.
Step-by-step explanation:
To determine the percent discount that the book club gave Henry given that you know the price of the cookbook and the amount of the discount, you can use a rule of three:
39.25 → 100%
3.19 → x
x=(3.19*100)/39.25
x=8.13%
According to this, the answer is that the book club gave Henry a 8.13% discount.
