Answer:
[tex]\begin{gathered} \text{The equation is} \\ 12x=30 \end{gathered}[/tex]Explanation:
Given that:
A flat of plant contains 12 plants.
1 flat plant = 12 plants
Yoshi wants a garden that has three rows with 10 plants per row.
That is;
10 plants times 3
which is 30 plants.
So, to know the number of flats Yoshi should buy. We use the equation
[tex]\begin{gathered} 1\text{ flat plant = 12 plants} \\ x\text{ flat plants = 30 plants} \end{gathered}[/tex]Where x is the number of flat plants Yoshi should buy.
The equation is now:
[tex]12x=30[/tex]..........................................................................................................................
Divide both sides by 12
[tex]\begin{gathered} x=\frac{30}{12} \\ \\ =\frac{5}{2} \end{gathered}[/tex]
