I don't know the answer to this one, sorry
Answer:
A) 

Step-by-step explanation:
When given a balanced scale (represented by a hanger in this image), the sum of the values on one side equals the value on the other side. Thus, the equation that this hanger represents is the following:

Use inverse operations to solve this equation,



Answer:
Step-by-step explanation:
<em>See the attached.</em>
The path goes along the perimeter of the park and parallel to the sides, something like the picture attached.
<u>The path is 1 m wide and the total length is:</u>
We need to consider the dark cells points in the picture with reflects the overlaps. They are counted twice and each is 1 m x 1 m.
<u>Subtracting the duplicated area 9 x 1 m² to get the total area of the path:</u>
<u>The cost of cementing is:</u>
Answer:
n must be 3
Step-by-step explanation:
The formula for the perimeter of a rectangle of length L and width W is
P = 2L + 2W. Substituting (1/2)(n - 6) for L and 2n + 5 for W, we get:
P = 60 = n - 6 + 4n + 10, or:
60 = 5n + 4, or:
15 = 5n
Then n must be 3.
