@Hero

Answer 2

when adding/subtracting with signs....if the signs are the same, add them and use the same sign. If the signs are different, subtract them and use the sign of the bigger number.

Answer 3

i think D or A mostly D

Answer 4

think about it....the signs are the same....so they are to be added and you would use the same sign....so it would be - 9.32....understand ?

Answer 5

It can get a little confusing because adding/subtracting with signs has a whole different set of rules then multiplying/dividing with signs

Answer 6

Answer 7

it is A....signs are the same...so you add and keep the same sign

Answer 13

Answer 15

Evaluate m – n when m = –1.5 and n = –7.7.

A.
–9.2

B.
–6.2

C.
6.2

D.
9.2

Answer 16

A?

Answer 17

ok...after subbing your problem becomes :
-1.5 - (-7.7).....little different here...we have to distribute the negative through the parenthesis changing the problem to : -1.5 + 7.7.....so the signs are different. So you subtract (7.7 - 1.5) and use the sign of the bigger number.

Answer 18

C the bigger number is positive

Answer 19

i might have done something wrong

Answer 20

correct :)

Answer 21

because the -7.7 became + 7.7 making the sign positive

Answer 22
