Sagot :

Horizontal addition

Row 1 a + 12 + b +6 =37

[tex]\begin{gathered} a+12+b+6=37 \\ a+b+18=37 \\ a+b=37-18 \\ a+b=19 \end{gathered}[/tex]

Row 2

[tex]\begin{gathered} 8+c+16+11=d \\ c+35=d \end{gathered}[/tex]

Row 3

[tex]\begin{gathered} 17+5+e+18=f \\ 40+e=f \end{gathered}[/tex]

Row 4

[tex]\begin{gathered} g+34+45+h=143 \\ g+h+79=143 \\ g+h=143-79 \\ g+h=64 \end{gathered}[/tex]

Now Let us add the columns

Column 1

[tex]a+8+17=g[/tex]

Column 2

[tex]\begin{gathered} 12+c+5=34 \\ c+17=34 \\ c=34-17 \\ c=17 \end{gathered}[/tex]

Column 4

[tex]\begin{gathered} 6+11+18=h \\ h=35 \end{gathered}[/tex]

Column 2

[tex]\begin{gathered} b+16+e=45 \\ b+e=45-16 \\ b+e=29 \end{gathered}[/tex]

Hence, Video games under 10-12 is c=17, gotten from column 2

Vertical total under 16-18 is h=35 gotten from column 4

Hence, the horizontal total of the video game is 52

Since h is gotten, we can solve for 7 to 9 vertical total

[tex]\begin{gathered} g+h=64 \\ g=64-h \\ g=64-35 \\ g=29 \end{gathered}[/tex]

Hence, the 7 to 9 vertical total is 29

[tex]\begin{gathered} a+25=g \\ a=g-25 \\ a=29-25 \\ a=4 \end{gathered}[/tex]

Hence, Darts under 7 to 9 is 4

Darts under 13 to 15 is b

[tex]\begin{gathered} a+b=19 \\ b=19-a \\ b=19-4 \\ b=15 \end{gathered}[/tex]

Hence, Darts under 13 to 15 is 15

Basket ball under 13 to 15 is e

[tex]\begin{gathered} b+e=29 \\ e=29-b \\ e=29-15 \\ e=14 \end{gathered}[/tex]

Hence, Darts under 13 to 15 is 14

Video Games Horizontal total is d,

[tex]\begin{gathered} c+35=d \\ 17+35=d \\ d=52 \end{gathered}[/tex]

Hence, the Horizontal total of the Video game is 52

Basketball horizontal total is f

40+e=f

[tex]\begin{gathered} 40+e=f \\ 40+14=f \\ 54=f \end{gathered}[/tex]

Hence, the horizontal total of the Video game is 54.

Hence, the above table fill the empty space
