Answer:

14 nickels

7 dimes

Step-by-step explanation:

1. find out how many dimes there has to be to get $1.40

1 dime= .10

1.40/.10=14 dimes

14/2=7

so there are 7 dimes

since a nickel is half the amount of a dime there will be twice as many to make up the other half which is $0.70

.70/.05=14

there are 14 nickels

proof:

$0.10(7)+$0.05(14)= $1.40

hope this helps!

What is the value of the expression 29-|7-11|
Makovka662 [10]

The value of 29 - |7 - 11| = 25

We have the following expression -

29 - |7 - 11|

We have to find its value.

<h3>Find the value of the expression -</h3><h3>X + | \piY |    where Y < 0</h3>

We have -

X + | \piY |

Since Y < 0 - therefore \piY < 0

Now -

|a| = - a   { for a < 0}

Therefore -

X -  \piY

According to the question, we have -

29 - |7 - 11|

29 - | -4 |

29 - 4

25

Hence, the value of 29 - |7 - 11| = 25
