The expression  -10 - (-4) represents the given diagram.

Step-by-step explanation:

Here, the total number of blue boxes marked with (-) = 10

So, in Total number of (-) are 10 x (-1) = -10

Now, the number of boxes crossed out = 4

So, the total value crossed out = 4 x ( Value on each box) = 4 ( -1) = -4

⇒ The value Left after crossing  = Total value - The crossed out value

                                                        = -10 - (-4)

Hence, the expression  -10 - (-4) represents the given diagram.

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.  

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
