Work: Find the solution of equation 175000000 = 13.8*300*a*(560-a/2) .
Question type: Equation
Solution:Original question:
| 175000000 | = | 69 5 | × | 300 | a | ( | 560 | − | a | ÷ | 2 | ) |
| Right side of the equation = | 4140 | a | ( | 560 | − | a | ÷ | 2 | ) |
| 175000000 | = | 4140 | a | ( | 560 | − | a | ÷ | 2 | ) |
| Right side of the equation = | 4140 | a | × | 560 | − | 4140 | a | a | ÷ | 2 |
| = | 2318400 | a | − | 2070 | a | a |
| 175000000 | = | 2318400 | a | − | 2070 | a | a |
a≈81.398979 , keep 6 decimal places
