Answer:
Step-by-step explanation:
7/8x + 4/5 = 1 3/10
[tex]\frac{7}{8}x+\frac{4}{5} =\frac{13}{10}[/tex]
[tex]\frac{35}{40}x+\frac{32}{40} =\frac{52}{40}[/tex]
[tex]40(\frac{35}{40}x+\frac{32}{40} =\frac{52}{40} )[/tex]
[tex]35x+32=52[/tex]
[tex]-32[/tex] [tex]-32[/tex]
[tex]35x = 20[/tex]
[tex]\frac{35x}{35} =\frac{20}{35}[/tex]
[tex]x=\frac{4}{7}[/tex]
4/5X + 4/9 = 1 3/10
[tex]\frac{4}{5} x + \frac{4}{9} = \frac{13}{10}[/tex]
[tex]\frac{72}{90} x + \frac{40}{90} = \frac{117}{90}[/tex]
[tex]90(\frac{72}{90} x + \frac{40}{90} = \frac{117}{90})[/tex]
[tex]72x+40=117[/tex]
[tex]-40[/tex] [tex]-40[/tex]
[tex]72x=77[/tex]
[tex]\frac{72x}{72}=\frac{77}{72}[/tex]
[tex]x=\frac{77}{72} =5\frac{5}{72} =1.07[/tex]
5/8X + 4/9 = 1 1/9
[tex]\frac{5}{8} x + \frac{4}{9} = \frac{10}{9}[/tex]
[tex]\frac{45}{72} x + \frac{32}{72} = \frac{80}{72}[/tex]
[tex]72(\frac{45}{72} x + \frac{32}{72} = \frac{80}{72} )[/tex]
[tex]45x+32=80[/tex]
[tex]-32[/tex] [tex]-32[/tex]
[tex]45x=48[/tex]
[tex]\frac{45x}{45}=\frac{48}{45}[/tex]
[tex]x=\frac{16}{15}[/tex]
Hope this helps!
