Answer 1

@jigglypuff314

Answer 2

transitive property is if a = b and b = c then a = c :)

Answer 3

is this one right @jigglypuff314

Answer 4

Correct! :)

Answer 5

@jigglypuff314

Answer 6

you can use the idea of vertical angles for this :)

vertical angles are congruent
so 7x + 7 = 112 solve for x :)

Answer 7

C

Answer 8

mmm not quite :)
could you solve for x from 7x + 7 = 112 ?

Answer 9

15

Answer 10

yep :)

Answer 11

yayyy!! :D

Answer 12

if y = -5
then you would plug in -5 for y into 7x + y = 11 right?
could you do that? :)

Answer 13

B :)

Answer 14

correct! :)

Answer 15

:D

Answer 16

well, you would want to first move the 9 to the other side since it was crowding the x/5 right?
and since it's crowding the x/5 by addition (+)
then you should use subtraction to undo it right? :)

Answer 17

i dont understand :s

Answer 18

well, for example if you had 2x + 5 = 11
and you want to get x alone, you want to move 5 to the other side
so since it's addition, you would subtract to move it
so 2x + 5 = 11
-5 -5
2x = 6

Answer 19

i think A

Answer 20

i mean D**

Answer 21

not quite :)

you would subtract 9 from both sides to move it right?

Answer 22

B :)

Answer 23

Correct :) Good Job! ^_^

Answer 24

yayy! :D

Answer 25

I've never learned Law of Detachment, sorry :/
but maybe this can help? http://wiki.answers.com/Q/What_is_the_Law_of_detachment

Answer 26

okay thank you :)

Answer 27

What is a counterexample for the conjecture? Conjecture: Any number that is divisible by 4 is also divisible by 8.
A. 24
B. 40
C. 12
D. 26

Answer 28

well you can test each :)
first pick out all the ones that are divisible by 4
then see which one out of then is not divisible by 8 :)

Answer 29

C

Answer 30

Correct! :)

Answer 31

are you sure that's the right picture? :/ I thought we did this one before?

Answer 32

yeah it is, we did a different problem tho

Answer 33

hmmm... you might want to scroll up and compare ^^^

Answer 34

oh. same question thats odd! it would be (B) again

Answer 35

yep :)

Answer 36

symmetric property is if a = b then b = a
transitive is if a = b and b = c then a = c
reflexive is a = a

Answer 37

A

Answer 38

yes :)

Answer 39

What is a counterexample for the conjecture? Conjecture: The product of two positive numbers is greater than the sum of the two numbers.
A. 3 and 5
B. 2 and 2
C. A counterexample exists, but it is not shown above.
D. There is no counterexample. The conjecture is true.

Answer 40

I"m not entirely sure about this one...
There is a counter example
because the positive numbers (1/2) and 4 work as counter
but since it didn't say "greater than or equal to"
then 2*2 = 4
and 2+2 = 4 might work too

Answer 41

hmmm i think B

Answer 42

Yeah, you can go with that ^_^
but if you get it incorrect by some chance, then it might have been C...

Answer 43

yeah okay :))

Answer 44

lol well... which one has addition in it? :P

Answer 45

B! sorry that one wasnt a question

Answer 46

ok :)

Answer 47

Identify the hypothesis and conclusion of this conditional statement: If two lines intersect at right angles, then the two lines are perpendicular.
A. Hypothesis: The two lines are perpendicular. Conclusion: Two lines intersect at right angles.
B. Hypothesis: Two lines intersect at right angles. Conclusion: The two lines are perpendicular.
C. Hypothesis: The two lines are not perpendicular. Conclusion: Two lines intersect at right angles.
D. Hypothesis: Two lines intersect at right angles. Conclusion: The two lines are not perpendicular.

Answer 48

hypothesis is the part that comes after "If"
and the conclusion part comes after "then" :)

Answer 49

B :)

Answer 50

correct :) and I gotta brb

Answer 51

thank you and okay :))

Answer 52

I'm back ^_^

Answer 53

do you still need help @lolipop98 ? :)

Answer 54

hey! and yes :) @jigglypuff314

Answer 55

got this one marked wrong

Answer 56

:/

Answer 57

:/ I don't see why... sorry :(

Answer 58

:/ its okay

Answer 59

hmm so it cant be D?

Answer 60

last step is definitely multiplication
... the only loophole might be adding a negative 9

Answer 61

yeah i thought the same thannk you :)

Answer 62

oh for that one, you can do down the line

angle b and angle h aren't vertical angles, so it eliminates option B

Answer 63

hmm i think

Answer 64

A

Answer 65

yep :)

Answer 66

woo hoo!

Answer 67

angles H and E are vertical angles, not alternate exterior,
so that eliminates A :)

Answer 68

none

Answer 69

hmmm I think so :)

Answer 70

yay!! :D is this one right

Answer 71

hmmm I think angle 6 = angle 3

Answer 72

im confused

Answer 73

ahhh i got it i think! its 42?

Answer 74

yes :)

Answer 75

Oh gosh, sorry I don't know them constructing stuff >,<

Answer 76

oh ahaah

Answer 77

by that definition, I don't see any in the options :)
