Question

a flat of plants contains 12 plants. yoshi wants a garden that has three rows with 10 plants per row. Write and solve an equation for the number of flats yoshi should buy. translate each sentence into an equation

Answer 1

`\begin{gathered} \text{The equation is} \\ 12x=30 \end{gathered}`

Step-by-step 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

`\begin{gathered} 1\text{ flat plant = 12 plants} \\ x\text{ flat plants = 30 plants} \end{gathered}`

Where x is the number of flat plants Yoshi should buy.

The equation is now:

`12x=30`

..........................................................................................................................

Divide both sides by 12

`\begin{gathered} x=(30)/(12) \\ \\ =(5)/(2) \end{gathered}`
