Answer 4

A.
commutative property

Answer 5

A? im not good with math

Answer 6

that's right!

Answer 7

oh i pressed enter

Answer 8

lol i have 4 more plz

Answer 9

ok!

Answer 10

Which is an example of the opposite of a sum property?

A.
–17 + 32 = 32 + (–17)

B.
–26 + (4 + 8) = (–26 + 4) + 8

C.
–5(6 + 3) = –5(6) + –5(3)

D.
–(–17 + 5) = 17 + (–5)

Answer 11

i think D

Answer 12

in general the opposite of a sum is given by the subsequent formula:
\[ - \left( {a + b} \right) = - a - b\]
where a qnd b are two real numbers

Answer 13

and*

Answer 14

so, you are right!

Answer 15

What is the value of the expression?

12.4 + (–2 + 1.6)

A.
11

B.
12

C.
15

D.
16

Answer 16

we have to solve the computation inside the parentheses, so we have:
12.4+(-2+1.6)=12.4+(-0.4)=12.4-0.4=...?

Answer 17

i think B

Answer 18

that's right!

Answer 19

What value of q makes the statement true?

–(q + 14) = –3 + (–14)

A.
–17

B.
–3

C.
3

D.
17

Answer 20

at the rigt side we can write this:
-3+(-14)=-3-14=...?
please complete

Answer 21

right*

Answer 22

-3+(-14)=-3-14=im thinking

Answer 23

ok! and what is -3-14=...?

Answer 24

wait i think A

Answer 25

am i correct

Answer 26

more precisely:
right side= -17
now we can rewrite your original expression, as below:
-(q+14)=-17
from which I can write this:
q+14=17
so, what is q?

Answer 27

-17

Answer 28

we have to find a number which added to 14 gives 17. what is such number?

Answer 29

ok i had it but u r confusing me

Answer 30

3 i guess

Answer 31

q=3 because 3+14=17

Answer 32

ohhhh ok

Answer 33

that's right, your option is C

Answer 34

Use an addition property to solve for c.

14 + (–12) = –12 + c

A.
–26

B.
–14

C.
14

D.
26

Answer 35

last 1

Answer 36

if I apply the commutative property, I can write this:
14+(-12)=-12+14
so, what is c?

Answer 37

14=C

Answer 38

correct!!

Answer 39

yay i got a 100

Answer 40
