Oooh I don't know the exact wording, but it is the property that states that the order of the numbers in the equation can be switched and still equal the same thing as long as the signs are still kept.
Given :
A freight elevator has a weight limit of 15,000 pounds.
Workers have loaded items weighing 2.6 tons onto the elevator.
To Find :
How many more pounds of freight can they load before reaching the weight limit.
Solution :
We know, 1 ton = 2000 pounds.
So, 2.6 ton = 2.6 × 2000 = 5200 pounds.
Now, number of pounds of freight can be loaded before reaching the weight limit is :
N = 15000 - 5200 pounds
N = 9800 pounds
Set a proportion. They are similar triangles.
A because 1-10 would be -9 and she was a meter above so positive but they descended 10 meters no negitve
