Answer:

  630

Step-by-step explanation:

The sum of an arithmetic sequence is given by ...

  Sn = n(2a1 +(n-1)d)/2

For the sequence of numbers of bales, we have ...

  a1 = 123, d = -11, n = 7

so the total number of bales in 7 trips around the field is ...

  S7 = 7(2·123 +6(-11))/2 = 630

The total number of bales made is about 630.

_____

123 + 112 + 101 + 90 + 79 + 68 + 57 = 630

18 - (8 - 3 • (2t + 5)) = 0



6t + 25 = 0



3.1 Solve : 6t+25 = 0

Subtract 25 from both sides of the equation :
6t = -25
Divide both sides of the equation by 6:
t = -25/6 = -4.167

Final answer is

t = -25/6 = -4.167
