2 answers:
(-3.4x+4.7)-(3+2.9x)=
distribute
-3.4x +4.7 - 3 -2.9x=
combine like terms
-3.4x -2.9x +4.7 -3
-6.3x+1.7
First you need to remove the parenthesis ,and then combine or put together the like terms .Then after doing this you can find the difference:
-3.4x+4.7 - 3+2.9x
Next Simplify : -3.4x+4.7-3-2.9x:

I guess “1” is the minimum value
The first one is 24, and the second one is 12
From the question we can deduce the formula to be 16 + 3n = 76
3n - 76 - 16
3n = 60
n = 20
20 is the answer.
You cut out the question-
Well, the first one is 2/40=1/20. The 2nd one is 1/39. You multiply these to get 1/780.
