Answer:

y=1-7x

Step-by-step explanation:

7x+y=1

The first thing to do is get the y by its self. So u cancel the 7x out by-7x and bring it to the other side.

7x-7x = 0

Now all we have left is: y=1-7x

Hope it helps and is right.

A rectangular floor is 7 yd long and 3 yd wide. Heatherwants to tile the floor with tile sold by the square foot.Use the facts t
Sonja [21]

We need to convert the given measures from yard to feet. Since 1 yard is equal to 3 feet, we have

\begin{gathered} 7yd=7yd\times(\frac{3ft}{1yd}) \\ \text{then} \\ 7yd=21ft \end{gathered}

similarly, for the wide, we have

\begin{gathered} 3yd=3yd\times(\frac{3ft}{1yd}) \\ 3yd=9ft \end{gathered}

Since the area of a rectangle is wide times length, the area is

\begin{gathered} A=\text{wide}\times length \\ A=9ft\times21ft \\ A=189ft^2 \end{gathered}

Therefore, the area is equal to 189 square feet
