Answer:

  • commutative property
  • distributive property

Step-by-step explanation:

The expression

  4.7x + 10.4 + 15.3x − 8.4x + 15.6

can be simplified in a few stages. First of all, we use the commutative property of addition to swap terms 2 and 3.

  4.7x +15.3x +10.4 -8.4x +15.6

Next, we use the distributive property to factor x from the first two terms.

  (4.7 +15.3)x +10.4 -8.4x +15.6

Now we perform addition.

  20x +10.4 -8.4x +15.6 . . . . . . . . equivalent expression

krok68 [10]

Answer: 250 miles

Step-by-step explanation:

I am not sure what grade level you are, but this is how it is done in college.

I hope it can give you an idea and be of some help.

First you have to convert 150 minutes to hours. Then you multiply your new hours to 100 miles.

150 minutes x <u>     1 hour     </u> x<u>       100 miles    </u>= 250 miles

                           60 mins.              1 hour

SashulF [63]

Answer:

1.0638

Step-by-step explanation:

Given the question:

If a mechanic is applying 12 Newton centimeters of torque on a bolt how many pound inches would this be?

Torque = 12 Newton centimeter

Torque which is the turning effect on an object :

1 Newton = 0.225 pound force

1 centimeter = 0.394 inch

Hence ;

1 Newton centimeter = (1 × 0.225 × 0.394) = 0.08865 pound inch

12 Newton centimeter is hence, equals :

(12 × 0.225 × 0.394) pound inch

= 1.0638 pound inch
