The expression b/c=b/c is an example of a(n)?

bc=cb

It is an example of commutative property.

Step-by-step explanation:

The given expression

By cross multiplying we can write given expression as

  a+b=b+a

We can write commutative property in multiplication

        ab=ba

Therefore, by using commutative property  then we get

         bc=cb

Hence, the given expression is an example of commutative property.

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

it would take 7/10 of an hour too fill the pool.
