Need with problem 40,41 and 42! 15 points

40) w = 32/3

41) x = 23/4

42) w = 1/12

Step-by-step explanation:

40) Real world problem:

If Lisa takes of the pie from a total of slices, then the remaining pie is . Find w.

So, the equation would become:

This can be written as:

This is equivalent to

Since, the denominator is the same, the numerators can be added now.

Hence, the answer is 32/3.

41) The given equation is:

and

So,

The answer is 23/4.

42) The given equation is

The answer is 1/12.

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5
