Answer:
Converse: If two angles are supplementary then they add up to 180 degrees.
Inverse: If two angles are not supplementary then they do not add up to 180 degrees.
Contrapositive: If angles do not add up to 180 degrees, then the two angles are not supplementary.
Step-by-step explanation:
In logic the converse of an implication is obtained by reversing its two constituent statements. That is, for P → Q, then the converse is Q → P.
The inverse of a conditional statement involves the negation of both the hypothesis and conclusion. That is, for p → q, the Inverse is ~p → ~q note that ~ stands for NOT in the negation of the statement.
For a contrapositive of any conditional statement, we interchange the hypothesis and the conclusion of the inverse statement as shown in statement III in the answer above.

I need to find out what makes m ll n I’m in geometry and this is big ideas please help if can
============================================
Explanation:
On that diagram, the unmarked angle above the (6x-8) is equal to (5x+12). This is because the unmarked angle and the angle marked with (5x+12) are corresponding angles. Corresponding angles must be congruent if you want line m to be parallel to line n.
From here we add up (5x+12) and (6x-8) and set that sum equal to 180. Solve for x
We get the following:
(5x+12)+(6x-8) = 180
5x+12+6x-8 = 180
(5x+6x)+(12-8) = 180
11x+4 = 180
11x = 180-4
11x = 176
x = 176/11
x = 16

Look at this information about recycling:
20 large plastic bottles can be recycled to make 1 fleece jacket
How many fleeces can be made with 280 large plastic bottles?
Answer:
14 fleeces can be made from 280 large plastic bottles.
Step-by-step explanation:
Given that:
20 large plastic bottles can be recycled to make 1 fleece jacket.
Ratio of bottles to jacket = 20:1
Number of large plastic bottles = 280
Let,
x be the number of fleece jackets.
Ratio of large bottles to fleece jackets = 280 : x
This is a proportional relationship.
20 : 1 :: 280 : x
Product of mean = Product of extreme
280 = 20x
20x = 280
Dividing both sides by 20
[tex]\frac{20x}{20}=\frac{280}{20}\\x = 14[/tex]
Hence,
14 fleeces can be made from 280 large plastic bottles.

X + 2= 45
What’s the answer
Answer:
X = 43
Step-by-step explanation:
X + 2 = 45
X + 2 - 2 = 45 - 2
All you have to do is add 2 more to 43 and you'll get 45, so 43 is your answer.
7x - 4 + = 12 show me the steps
Answer:
impossible, but two ways:
either:
x=16/7
or:
7x+8
Step-by-step explanation:
if it is 7x-4+12, then it is 7x+8 because it is an expression.
If it is 7x-4=12, then it is x=16/7 because it is an equation.
otherwise, it is python programming or impossible.
Write an equation where a number is added to a variable, and a solution is -8.

Given:
32 and 28 are the two numbers.
To find:
(a) The GCF of 32 and 28.
(b) Using the GCF, find the factor of (32-28).
Solution:
(a)
The factor forms of the given numbers are:
[tex]32=2\times 2\times 2\times 2\times 2[/tex]
[tex]28=2\times 2\times 7[/tex]
It is clear that, 2 and 2 are the common factors in both.
[tex]GCF(32,28)=2\times 2[/tex]
[tex]GCF(32,28)=4[/tex]
Hence, the GCF of 32 and 28 is 4.
(b)
Using the GCF we need to find the factor of (32-28).
[tex]32-28=4\times 8-4\times 7[/tex]
Taking out the GCF, we get
[tex]32-28=4\times (8-7)[/tex]
Hence, [tex]32-28=4\times (8-7)[/tex].
Subtracting Radicals
Combine the radicals gvx-37x.
5rx
–6/2x
-6
Given:
The expression is
[tex]9\sqrt{x}-3\sqrt{x}[/tex]
To find:
The result after subtracting the radicals.
Solution:
We have,
[tex]9\sqrt{x}-3\sqrt{x}[/tex]
We need to combine these terms.
Taking out common factors, we get
[tex]=(9-3)\sqrt{x}[/tex]
[tex]=6\sqrt{x}[/tex]
The result after subtracting the radicals is [tex]6\sqrt{x}[/tex].
Therefore, the correct option is B.

Scale drawing of the gym.
A rectangle with length 9 centimeters and width 4 centimeters.
StartFraction 1 centimeter over 10 meters EndFraction = StartFraction 9 centimeters over new length EndFraction. (1) (new length) = (10) (9). New length = 90 meters.
Using the scale 1 cm : 5 meters, Tamara calculated the length of her old gym to be 45 meters and the width to be 20 meters.
Using a new scale, 1 cm : 10 meters, she found the length of the new gym to be 90 meters.
The width of the new gym is
meters.
The length and width of the new gym are

Find the values of k so that each remainder is three.
10. (x^2+ 5x + 7) = (x + k)
Answer:
[tex]k=1\text{ or } k=4[/tex]
Step-by-step explanation:
We can use the Polynomial Remainder Theorem. It states that if we divide a polynomial P(x) by a binomial in the form (x - a), then our remainder will be P(a).
We are dividing:
[tex](x^2+5x+7)\div(x+k)[/tex]
So, a polynomial by a binomial factor.
Our factor is (x + k) or (x - (-k)). Using the form (x - a), our a = -k.
We want our remainder to be 3. So, P(a)=P(-k)=3.
Therefore:
[tex](-k)^2+5(-k)+7=3[/tex]
Simplify:
[tex]k^2-5k+7=3[/tex]
Solve for k. Subtract 3 from both sides:
[tex]k^2-5k+4=0[/tex]
Factor:
[tex](k-1)(k-4)=0[/tex]
Zero Product Property:
[tex]k-1=0\text{ or } k-4=0[/tex]
Solve:
[tex]k=1\text{ or } k=4[/tex]
So, either of the two expressions:
[tex](x^2+5x+7)\div(x+1)\text{ or } (x^2+5x+7)\div(x+4)[/tex]
Will yield 3 as the remainder.
