Answer

Find out the total number of minutes they played using associative property.

To proof

Associative property of addition

This property states that

a + ( b + c) = ( a +b) +c

Where a, b, c are the any numbers.

As given

Sophia Played for 18 minutes and 26 minutes last week should play the piano for 40 minutes last week

let

a =  18 minutes , b =  26 minutes , c =  40 minutes

Total number of minutes sophia played = a + ( b + c) = ( a +b) +c

put the value of a, b,c

Total number of minutes sophia played =18+(26 +40) = (18 +26) + 40

                                                                  = 18 +66 = 44 + 40

                                                                  = 84 = 84

satisfy the associative property

Therefore the total number of minutes sophia played be 84 mintues.

Hence proved

John borrows $6.50 from his friends to pay for snacks, and $11.75 from his sister to go to the movies how much money does he nee
Nina [5.8K]

John has borrowed $6.50 from his friends and $11.75 from his sister. To find how much money he needs to repay you can just add up the amount of money he has borrowed.

Make an equation to solve for this, where x = amount of money John needs to repay. Make the amount of money John borrowed add up to x. Your equation should look like:

$6.50 + $11.75 = x

Combine like terms (add 6.50 and 11.75).

$18.25 = x

After solving the equation, you have figured out that John need to repay $18.25 in total.

The Price of Car A rounded to the Nearest £100 is £12400

The Price of Car B rounded to the Nearest £100 is £16800

The Price of Car C rounded to the Nearest £100 is £14600

Difference between the Rounded Price and Original Price of Car A :

⇒ (£12400 - £12380) = £20

Difference between the Rounded Price and Original Price of Car B :

⇒ (£16800 - £16760) = £40

Difference between the Rounded Price and Original Price of Car C :

⇒ (£14600 - £14580) = £20

From the above, We can Notice that :

The Price of Car B changes by the greatest amount.
