Work: Find the solution of equation 50000 = (150+x)*3.14*(x/9) .
Question type: Equation
Solution:Original question:
| 50000 | = | ( | 150 | + | x | ) | × | 157 50 | ( | x | ÷ | 9 | ) |
| Right side of the equation = | 150 | × | 157 50 | ( | x | ÷ | 9 | ) | + | x | × | 157 50 | ( | x | ÷ | 9 | ) |
| = | 471 | ( | x | ÷ | 9 | ) | + | x | × | 157 50 | ( | x | ÷ | 9 | ) |
| = | 471 | x | ÷ | 9 | + | x | × | 157 50 | ( | x | ÷ | 9 | ) |
| = | 157 3 | x | + | x | × | 157 50 | ( | x | ÷ | 9 | ) |
| = | 157 3 | x | + | x | × | 157 50 | x | ÷ | 9 |
| = | 157 3 | x | + | x | × | 157 450 | x |
| 50000 | = | 157 3 | x | + | x | × | 157 450 | x |
the solutions is:
x≈310.923700 , keep 6 decimal places
There are 1 solution(s).
