solvefor c, 114982/3cm^3= 4/322/7r^3

解答

求解

c, \frac{114982}{3} \cdot c \cdot m^{3} = \frac{4}{3} \cdot \frac{22}{7} \cdot r^{3}

c = \frac{44 r ^{3}}{402437 m ^{3}}; m \neq = 0

求解步骤

\frac{114982}{3} c m^{3} = \frac{4}{3} \cdot \frac{22}{7} r^{3}

分式相乘:

\frac{a}{b} \cdot \frac{c}{d} = \frac{a \cdot c}{b \cdot d}

\frac{114982}{3} c m^{3} = \frac{4 \cdot 22}{3 \cdot 7} r^{3}

\frac{4 \cdot 22}{3 \cdot 7} = \frac{88}{21}

\frac{114982}{3} c m^{3} = \frac{88}{21} r^{3}

在两边乘以

3

114982 m^{3} c = \frac{88}{7} r^{3}

两边除以

114982 m^{3}; m \neq = 0

c = \frac{44 r ^{3}}{402437 m ^{3}}; m \neq = 0

so l v e f or x, (f) + 4 f = x - 2

so l v e f or g, g (s) = k (s + 2) (s^{2} - 4 s + 13)

so l v e f or x, 2 x^{1} - m (x - 1) = 0

x - a = 24

- 6 x - 4 = - 2 x - 9
