Answer:
Mind Strainers
1. 120
Solution:
[tex]t=rs(s+1)\\t=(4)(5)(5+1)\\t=(20)(6)\\t=120[/tex]
2. [tex]\frac{-9}{16}[/tex]
Solution:
[tex]k=\frac{6-5q}{2g} \\\\k=\frac{6-5(3)}{2(8)} \\\\k=\frac{6-15}{16} \\\\k=\frac{-9}{16}[/tex]
3. -3
Solution:
[tex]p=\frac{a+b-2c}{3} \\\\p=\frac{2+(-1)-2(5)}{3} \\\\p=\frac{2-1-10}{3} \\\\p=\frac{-9}{3} \\\\p=-3 \\\\[/tex]
4. [tex]\frac{7}{12}[/tex]
Solution:
[tex]l=\frac{1}{x} -\frac{2}{y}+z\\\\l=\frac{1}{4} -\frac{2}{6}+\frac{2}{3} \\\\l=\frac{1}{4} -\frac{1}{3}+\frac{2}{3} \\\\l=\frac{1}{4}(3) -\frac{1}{3}(4)+\frac{2}{3}(4)\\\\l=\frac{3}{12} -\frac{4}{12}+\frac{8}{12}\\\\l= -\frac{1}{12}+\frac{8}{12}\\\\l=\frac{7}{12}[/tex]
