9/10 = d/(6.4)

\frac{9}{10} = \frac{d}{6.4}

d = 5.76

Solution steps

\frac{9}{10} = \frac{d}{6.4}

Switch sides

\frac{d}{6.4} = \frac{9}{10}

Multiply both sides by

10

\frac{10 d}{6.4} = 9

Multiply both sides by

6.4

10 d = 57.6

Divide both sides by

10

d = 5.76

x^{2} + 6 x - 10 = 0

(3 + 3 i)^{3}

- 3 x < 9

\frac{1}{1 - \frac{2}{3}}

2 x + 7 = 2 x + 7
