Hi
-7c-5d/6c + 5c-9d/8c +1
So each code has a letter and number,(ex:1A2B, 2B3C, 3C4D)
To simplify 8d -5 +7d -9d, combine the numbers with the ds and don't forget the -5. 8d + 7d - 9d = 6d Simplified, it is 6d - 5.
It is: 14c-5c = 9c
It is 157.
-5c-6=29 29 + 6= 35 -5c=35 c=7
18
-1C is warmer than -5C.
whats 7c + 5c+=
There are 5 carbon atoms in 5C.
If that is an equation: 5c = 10 then the value of c is 2
9d-19=6d+2 ... add 19 to both sides and subtract 6d from both sides... 9d-6d=2+19 3d=21 d=21/3 d=7
