6 0

Answer:

x = 3, y=0

Step-by-step explanation:

2x + y =6

y = x-3

Substitute the second equation into the first

2x +x-3 =6

Combine like terms

3x-3 =6

Add 3 to each side

3x-3+3 = 6+3

3x= 9

Divide each side by 3

3x/3 = 9/3

x =3

Now we need to find y

y = x-3

y = 3-3=0

y=0

The diagram represents the shape and dimensions of Kayla's garden. A special fertilizer is used for the vegetable garden. Each b

Serjik [45]

Answer:

B. 18 bags

Step-by-step explanation:

First you need to determine the area of the vegetable garden. The vegetable garden is a rectangle with the following dimensions:

L = 24 ft

W = 9 ft

The Formula for the area of a rectangle is:

$A = L\times W$

So let's solve it:

$A = L\timesW\\A = 24 ft\times9ft\\A= 216ft^{2}$

With that, we can figure out how many bags of fertilizer would be needed by dividing the area of the vegetable garden by how much one bag of fertilizer covers:

$\dfrac{214ft^2}{12ft^2/bag}=18\;bags$

$\frac{6}{4}=\frac{2}{f}\\\frac{3}{2}=\frac{2*\frac{3}{2}}{f*\frac{3}{2}}\\\frac{3}{2}=\frac{3}{\frac{3}{2}f}\\2=\frac{3}{2}f\\2*\frac{2}{3}=\frac{3}{2}f*\frac{2}{3}\\\frac{4}{3}=f$
