Answer:

The total number of unbroken / working slots

Step-by-step explanation:

Given that Devin's DVD case has 3 rows of slots, but 5 slots are broken

Also given that the number of slots in a row is x

1 row has x slots

3 rows has y slots

on cross multiplication we get y = 3x

ie there are a total of 3x slots in the 3 rows

Given that out of these 3x slots 5 . of the slots are broken

Therefore the total number of working slots = total number of slots - number of slots which are broken

total number of working slots are = 3x - 5

Therefore the given expression is the number of working / good slots

Christian has a cookie recipe that yields four dozen cookies and calls for 2 1/4 cups white sugar and 3/4 cup brown sugar.cif ch
Paha777 [63]

The ingredients given are for 4 dozen cookies; however, Christian only want to make one dozen, meaning he requires only 1/4 the ingredients.

1/4 of 2 1/4 cups of while sugar is found the following way.

First, we write 2 1/4 as an improper fraction

2\frac{1}{4}=2+\frac{1}{4}=\frac{9}{4}

1/4 of this is

\frac{9}{4}\times\frac{1}{4}=\frac{9}{16}

Hence, Christian requires 9/16 cups of white sugar.

Similarly, the 1/4 of 3/4 cups of brown sugar is

\frac{1}{4}\times\frac{3}{4}=\frac{3}{16}

Hence, Chrisitan requires 3/16 cups of brown sugar.

Therefore, the total cups of sugar required is the sum of

\frac{3}{16}+\frac{9}{16}=\frac{12}{16}=\frac{3}{4}

3/4 cups of sugar.

Anestetic [448]

Answer:

But this condition is not feasible so, from given equation the value of D is not determine

Step-by-step explanation:

Given equation is :

\frac{d}{18} +3 = \frac{3d}{54} + 22

\frac{d}{18} - \frac{3d}{54} = 22 - 3

Or, \frac{3d -3d}{54} = 18

Or    0 = 18

But  0 ≠  18

but this condition is not feasible so, from given equation the value of D is not determine   .. Answer
