Ответ:
1)
- При x = −6,8: \(x+3,2=-6,8+3,2=-3,6\).
- При x = −3,2: \(x+3,2=-3,2+3,2=0\).
- При \(x=1\frac{1}{3}\): \(x+3,2=1\frac{1}{3}+3\frac{2}{10}=\frac{20}{15}+\frac{48}{15}=\frac{68}{15}=4\frac{8}{15}\).
2)
- При x = −2,6: \(-5x=-5\cdot(-2,6)=13\).
- При x = 0: \(-5x=-5\cdot0=0\).
- При x = 1: \(-5x=-5\cdot1=-5\).
- При \(x=2\frac{8}{15}\): \(-5x=-5\cdot2\frac{8}{15}=-5\cdot\frac{38}{15}=-\frac{38}{3}=-12\frac{2}{3}\).
Ответ: 1) −3,6; 0; \(4\frac{8}{15}\). 2) 13; 0; −5; \(-12\frac{2}{3}\).
