Answer:

3

Step-by-step explanation:

A direct variation is of the form

y = kx

We know x and y so we can find k

81 = k *27

Divide each side by 27

81/27 = 27k/27

3=k

The constant of variation is 3

Your neighbor had to drop the selling price of her home from $180,000 to $165,000. What percent did the price get lowered? Round
Vikki [24]
You could do 165,000 divided by 180,000. This is 165000/180000, and that will give you the percentage that 165000 is of 180000 in decimal form, which is 0.9167.
Then we round to the nearest tenth, which is 0.92
0.92 as a percentage is 92%.
100% - 92% = 8%
The price of the home dropped by 8%.

A=c+(-10) Solve for c in terms of other variables.
True [87]
To do this we need to move 10 to other side.  To accomplish this you just need to add 10 to both side since (-10) 

so 
A+ 10 = c -10 + 10 
we get
A+ 10 = c

lets say it wasn't -10 but positive 10. 

A = c + 10  then we would subtract 10 from both sides

A -10 = c + 10 - 10 
we get 
A  - 10 = C
