169.80.235=F*0.33

解答

16 \cdot 9.8 \cdot 0.235 = F \cdot 0.33

F = \frac{18424}{165}

十进制

F = 111.66060 \dots

求解步骤

16 \cdot 9.8 \cdot 0.235 = F \cdot 0.33

交换两边

F \cdot 0.33 = 16 \cdot 9.8 \cdot 0.235

数字相乘:

16 \cdot 9.8 \cdot 0.235 = 36.848

F \cdot 0.33 = 36.848

在两边乘以

1000

330 F = 36848

两边除以

330

F = \frac{18424}{165}

\frac{( 5 x + 2 )}{3} - \frac{( x - 1 )}{2} = 5 + \frac{( x + 3 )}{4}

so l v e f or x, - 7 x + 3 y = 0

3 x - 2 - 2 x - 3 = 0

so l v e f or c, 4 c + 6 d = 20

\frac{1}{6} x - 4 = \frac{2}{3} x - \frac{1}{2}
