Answer: Michael has 87 comic books while David has 41 comic books.

Step-by-step explanation:

Let x represent the number comic books that Michael has.

Let y represent the number of comic books that David has.

Michael has 5 more comic books than double David's collection. The expression would be

x = 2y + 5

If together they have a total of 128 comics, it means that

x + y = 128- - - - - - - - - -1

Substituting x = 2y + 5 into equation 1, it becomes

2y + 5 + y = 128

3y + 5 = 128

3y = 128 - 5

3y = 123

y = 123/3

y = 41

Substituting y = 41 into x = 2y + 5, it becomes

x = 2 × 41 + 5

x = 87

shepuryov [24]

Answer:

Our expression is 205+2d where d is days past 60.

Step-by-step explanation:

Since the sunflower is 205 centimeters at 60 days, every day after 60 will be greater than 205. We will start with 205 in our expression.

205

Now, each day after 60 the sunflower grows 2 centimeters per day. So day 61 will be:

205+2

Day 62 will be:

205 +2+2

Notice, that for two days past 60, the sunflower has grown 2 times as much.

Our expression is 205+2d where d is days past 60.
