Answer:
8.9
Step-by-step explanation:
Parenthesis are always first so,
4.5+7.6=12.1
so the problem would look like this now:
12.1-8/2.5
so convert 8/2.5 to 8÷1/5÷2 so this will become 16/5
16.5 concerted to decimal=3.2
so 12.1-3.2=8.9

Answer:
d=3/5
Step-by-step explanation:
3 ( 4d + 1 ) - 9d = 6 - 2d
12d + 3 - 9d = 6 - 2d
12d - 9d + 2d = 6 - 3
5d = 3
d = 3/5
d = 0.6
