Answer 1

Ответ:

$\displaystyle \frac{a}{b} = 1 \frac{1}{3} \\ a - b = 8 \\ a = b + 8 \\ \frac{b + 8}{b} = \frac{4}{3} \\ 3b + 24 = 4b \\ b = 24 \\ a = 24 + 8 = 32 \\ otvet \: 24 \: u \: 32$

$\displaystyle x - y = \frac{8}{15} \\ x = 0.2 \times y \\ y = 5x \\ x - 5x = \frac{8}{15} \\ - 4x = \frac{8}{15} \: \\ x = - \frac{2}{15} \\ y = - \frac{2}{15} \times 5 = - \frac{10}{15} = - \frac{2}{3} \\ otvet \: - \frac{2}{15} \: u \: - \frac{2}{3}$

$\displaystyle \frac{11}{12} |x| + 5 \frac{5}{8} = 10 \frac{2}{3} \\ \frac{11}{12} |x|= 10 \frac{2}{3} - 5 \frac{5}{8} = 5 + \frac{2}{3} - \frac{5}{8} = 5 + \frac{16 - 15}{24} = 5 \frac{1}{24} \\ |x| = 5 \frac{1}{24} \div \frac{11}{12} = \frac{121}{24} \times \frac{12}{11} = \frac{11}{2} = 5.5 \\ x = 5.5 \: \\ x = - 5.5 \\ otvet \: x = 5.5 \: x = - 5.5$

$\displaystyle 8500 \times (1.03) {}^{2} = 9017.65 pyb$
