Answer:

3 hours 5 minutes

Step-by-step explanation:

Had he skied 5 minute longer, he would have skied for 4 hours, leaving 3 hours for snowboarding. Since he skied 5 minutes less than 4 hours, he snowboarded 5 minutes more than 3 hours.

You can also just subtract the times.

7 hours - 3 hours 55 minutes =

= 6 hours 60 minutes - 3 hours 55 minutes

= 3 hours 5 minutes

Answer: 3 hours 5 minutes

Simplify the following expression. 3 2/5x3(-7/5)
Studentka2010 [4]

The simplified expression of 32/5 x 3(-7/5) is  -672/25

<h3>How to simplify the expression?</h3>

The mathematical expression is given as:

32/5 x 3(-7/5)

Evaluate the product of 3 and -7/5

32/5 x 3(-7/5) =  32/5 x -21/5

Evaluate the product of 32 and -21

32/5 x 3(-7/5) =  672/5 x -1/5

Evaluate the product of 5 and 5

32/5 x 3(-7/5) =  672/25 x -1

So, we have:

32/5 x 3(-7/5) =  -672/25

Hence, the simplified expression of 32/5 x 3(-7/5) is  -672/25

Which expression uses the distributive property to represent the sum of 39 + 27
aalyn [17]

Answer:

The expression that uses the distributive property to represent the sum of 39 + 27 is 3(13 + 9)

Step-by-step explanation:

Given

Expression: 39 + 27

Required

Express using the distributive property

The distributive property is represented in the form a(b + c)

So, we can say that the meaning to the question is that the given expression should be represented in the form a(b+c)

Equate these two expressions, we have

a(b+c) = 39 + 27

Factorize the expression on the left hand side

a(b+c) = 3(\frac{39}{3} + \frac{27}{3})

Simplify fraction

a(b+c) = 3(13 + 9)

Compare expression on left hand side with the expression on the right hand side.

Since, they have the same format, then we've arrived at the answer.

Hence, the expression that uses the distributive property to represent the sum of 39 + 27 is 3(13 + 9)
