Tolong bantu ya pakai cara
Penjelasan dengan langkah-langkah:
1
[tex] \frac{x}{x - 3} = \frac{8}{6} \\ 6x = 8x - 24 \\ 6x - 8x = - 24 \\ - 2x = - 24 \\ x = 12 cm[/tex]
2
[tex]a) \: \frac{x}{x + 3} = \frac{10}{12} \\ 12x = 10x + 30 \\ 12x - 10 \times = 30 \\ 2x = 30 \\ x = 15cm \\ b)qc = x + 3 \\ = 15 + 3 = 18cm[/tex]
3
[tex]a) \frac{pk}{8} = \frac{7.5}{10} \\ pk = \frac{8 \times 7.5}{10} = 6cm \\ b) \frac{rs}{10} = \frac{5}{8} \\ rs = \frac{10 \times 5}{8} = 6.25cm[/tex]
