Answer :
3a - 4p + 3m
So you have to substitute the variables, by its numbers:
3(5.6) - 4(4.3) + 3(4)
Now multiply:
16.8 - 17.2 + 12
Now add or subtract from left to right
-0.4+12
=11.6
Your final answer is:
11.6

Answer:
11.6
Step-by-step explanation:
The first thing you must do is to substitute the variables with your numbers.
3a 4p 3m
3(5.6) - 4(4.3) + 3(4)
Next, you multiply the number in parentheses with the numbers you just substituted.
3(5.6)=16.8
4(4.3)=17.2
3(4)=12
Now you have
16.8 - 17.2 + 12
Subtracting 16.8 from 17.2 will give you −0.4
And finally, adding −0.4 + 12 will give you 11.6 :)
