Answer:
1. 11
2. -74
3. 8/15
4. 0
5. 1
Step-by-step explanation:
[tex]3x + 5 \\ = 3(2) + 5 \\ = 6 + 5 \\ = 11[/tex]
[tex]5xy + x - 4 \\ = 5( - 3)(5) + 5 - 4 \\ = - 75 + 5 - 4 \\ = - 75 + 1 \\ = - 74[/tex]
[tex] \frac{6ab - c}{abc} \\ = \frac{6(5)(3) - 10}{(5)(3)(10)} \\ = \frac{90 - 10}{150} \\ = \frac{80}{150} \\ = \frac{8}{15} [/tex]
[tex]3(xy + 6) \\ = 3( ( - 6)(1) + 6) \\ = 3( - 6 + 6) \\ = 3(0) \\ = 0[/tex]
[tex] \frac{2x + 5}{3x - y} \\ = \frac{2( - 3) + 5}{3( - 3) - ( - 8) } \\ = \frac{ - 6 + 5}{ - 9 + 8} \\ = \frac{ - 1}{ - 1} \\ = 1[/tex]
