Question

HELP When solving the equation ½t = -7, the next logical step is multiply both sides of the equation by 2. The justification is the

Answer 1

Because multiplying 1/2 by 2 will give 1
That will make the eqaution t=-7*2
t=-14

Answer 2

it's asking for a reasoning :/ Reflexive Property of Equality
Symmetric Property of Equality
Subtraction Property of Equality
Multiplication Property of Equality

Answer 3

It's a property of equality (since you're doing something to both sides of an equation)

Answer 4

the question is what are you doing to both sides?

Answer 5

it's not a trick question (well I hope it doesn't seem that way)

Answer 6

reflexive?

Answer 7

I think it is the Multiplication Property of Equality

Answer 8

you're reflexing each side?

Answer 9

no your multiplying :D

Answer 10

by 2

Answer 11

so it's the multiplicative property of equality

Answer 12

that says if you have a = b

then you can multiply both sides by c to get c*a = c*b

Answer 13

thank you so much :D best helper i seen on this site :D

Answer 14

yw

Answer 15

can you help me on one more it's a drawing :/

Answer 16

alright go for it

Answer 17

i think its definition :/ not 100 percent sure though

Answer 18

nope it's not that and it's not the symmetric property either

Answer 19

when you say "the measure of angle 1 + the measure of angle 2", you are basically adding the two angles

because they are adjacent angles, they form a larger angle (think of them glued together)

Answer 20

so which property am I describing?

Answer 21

angle addition -___-

Answer 22

yep

Answer 23

sorry for these really simple questions

Answer 24

a lot of these have descriptive names so they are probably deceptively simple

Answer 25

its fine, you're just second guessing yourself

Answer 26

i think it might be segment addition

Answer 27

no you're still adding angles

Answer 28

not segments

Answer 29

lol -___- transitive prop of congruence

Answer 30

technically it should be "the definition of complementary angles", but the next best thing is "angle addition postulate"

because you're basically exploiting the fact that the two add to 90 degrees

Answer 31

@arkoffusion If you don't know and ask, it is fine. That is how you learn. It is if you don't ask that it is a problem! So don't apologize for simple questions. It is still an important part of learning!
