Question: Im stuck if anyone could help that would be great
Answers:
13+(-12) is like as 13-12 which is 1
1-(-5)
two negatives take home a positive so this really means
1+5 which equals 6
C.
6
It's c, 6.
13 + (-12) give you 1.
1 - (-5) is basically totalling 5.
(when you say minus something unenthusiastic, switch both signs to positive).
1+ 5 is 6.
C.
its c.6
30
6, C
When subtracting a negative number, it act just as count a positive.
So -12 - -5 = -7
-7 + 13 = 6
The answer is c. Essentially, the -12 - -5 is the same piece as saying -12 + 5 (because of the double negative). So, that's -7. The put in that to 13, and you get positive 6.
13-12+5=
1+5=
6= C
c. 6
13 + (-12) - (-5)
13 - 12 - (-5)
First: combine the first two expressions...
1 - (-5)
Sec: eliminate the parenthesis --- distribute the gloomy sign with the possession in parenthesis...
1 + 5
= 6
c
It's 6
Two negative give a positive (oh Yeah )
The rule is that resembling signs give plus and unlike signs hand over minus so:
13+(-12) are unlike signs and so is the same as 13-12
-(-5) are close to signs and so is the same as +5
Thus, 13-12+5 = 6
c=6
13 + (-12) - (-5)=
13 -12 +5 =
1 + 5=
6.
6
13+(-12)-(-5)=
13-12+5 = 6
Answer c)6.
