Answer:
65 dm and 52 dm
Step-by-step explanation:
If the scale factor of the sides is k, then the scale factor of the areas is k^2.
The scale factor of the areas is (32 dm^2)/(50 dm^2) = 0.64 = k^2
The scale factor of the sides is k = \sqrt(0.64) = 0.8
The perimeters are in a ratio of 1:0.8
x + 0.8x = 117
1.8x = 117
x = 65
0.8x = 0.8(65) = 52
The perimeters are 65 dm and 52 dm.
Maybe the price of the fourth pair is like about fifty dollars because the average of the four shoes are fifty dollars. The other shoe pairs that he/she bought is thirty five, forty and fifty dollars.
So, the price is about fifty dollars.
First, you want to even out each side.

You need to inverse -q to +q and add to both sides to get

Now you need to do the oppisite of add to 11 which is subtract it from both sides.
