Answer:

7.9

Step-by-step explanation:

$2.25(a + 1.3) = 20.7 \\ \\ \implies a+ 1.3 = \frac{20.7}{2.25} \\ \\ \implies a+ 1.3 = 9.2 \\ \\ \implies a= 9.2 - 1.3 \\ \\ \implies a= 7. 9\\ \\$

How would u convert 5 feet 6 inches in inches

vitfil [10]

1 feet is 12 inches.

We have 5 feet and 6 inches. First, let's convert the feet to inches. 5 times 12 is 60, so 5 feet is 60 inches.

Now add 60 inches to the 6 inches that we didn't mention. 60 plus 6 is 66. Thus, 5 feet and 6 inches is 66 inches.

4. The length of your rectangular vegetable garden

OleMash [197]

The area of a garden is the amount of space the garden occupies

The area of the garden is (c) 375 ft^2

The given parameters are:

$L = 15 \times W$ --- Length equals 15 times width

$Perimeter=160$

The perimeter of a rectangle is:

$Perimeter= 2(L + W)$

Substitute known values

$160= 2(15 \times W + W)$

Divide through by 2

$80= 15 \times W + W$

$80= 15W + W$

$80= 16W$

Divide through by 16

$5= W$

Rewrite as:

$W =5$

The area of a rectangle is:

$Area = L \times W$

Substitute $L = 15 \times W$

$Area = 15 \times W \times W$

Substitute $W =5$

$Area = 15 \times 5 \times 5$

$Area = 375$

Hence, the area of the garden is (c) 375 ft^2
