Answer:

Hopefully you have theorem names in your notes, most of these aren't EXACT.

1. Given

2. Don't know EXACT theorem, but seems to have to do with a definition of congruent angle segments.

3. they both match on opposite sides so they are congruent, don't remember theorem name

4. Don't remember this kind of supplementary angle but they are supposed to add up to 180 so something with 180 degree supplementary angle

5. Alternate interior angles (opposite sides while staying inside)

6. Alternate exterior angles

7. don't know name but has to do with the fact that 2/3 angles for the triangles are solved for BOTH and are the SAME, making them congruent.

8. don't know theorem name but the 2 angles make the same value on both segments.

9. same as #8

10. you could say these are parallel if the measurements of the inside figure are the same on top as on bottom. (don't remember theorem name)

11. Same here as #10 except now it's the whole segment.

12. Definition of either a Parallelogram or Rhombus, assuming Parallelogram, don't have exact measurements.

Step-by-step explanation:

I didn't do many proofs when I took Geometry because they're basically useless but... here it is again.

Answer:

2 1/2 I think

Step-by-step explanation:

you find the L.C.M for all the fractions and multiply it. You should end up with whole numbers.

It should look like this

2n+3n=2

n= <u>2n+3n</u><u> </u> = <u>5</u>

2 2

n= 2 1/2

Three times the sum of 4 and a number is twice the<br> number. Find the number.
zavuch27 [327]

Step-by-step explanation:

let number be x

3(4+x)=2x

12 + 3x = 2x

12 = 2x - 3x

12 = -x

x= -12

Write 0.43 as a fraction, reduced to the lowest terms​
alexdok [17]

Answer:

43/100

Step-by-step explanation:

It would have to be 43/100 becuase 43 is a prime number, therefore it cannot be simplified.

3-14 plzzz except #13 20 points!
Marianna [84]
#3: 15

#4: 13.2

#5: 5.44 (curious as to how you guessed 7)

#6: 7

#7: 7.3

#8: 15

#9: You'd round 0.9 to 1 and 3.78 to 4. 4/1 = 4

#10: Round 2.5 to 3. 36/3 = 12

#11: If they want you to round 0.25 down to 0, then 7/0 is undefined. 

#12: 9.5 rounds to 10 142.5 rounds to 143. 143/10 = 14.3

#14: 24.8 cm divided by 175 = approximately 0.1417 cm per year. Round that up to approximately 0.14 per year.

Find the equation of a line given that: slope =5, y-intercept is (0,4). Standard form or slope intercept form?
Pie
So the slope is 5 and you know the points, (0,4)
y-4=5(x-0)
y-4 = 5x
y = 5x + 4 is the slope intercept form
standard form is: -5x + y = 4 OR y - 5x = 4
