Molly is baking oatmeal raisin cookies and chocolate chip cookies. she has no more than 10 cups of flour. a batch of oatmeal raisin cookies, r, takes 1 and 1/2 cups of flour and a batch of chocolate chip cookies, c, takes 2 cups of flour. which of these best represent the amount of flour available for molly to use in her cookies?

group of answer choices

a. 7/2 (r+c) > 10
b. 3/2 r < 10+2c
c. 2c=10-3/2r
d. 3/2r+2c< 10

a and d both have lines under the greater than or less than signs.

will mark brainliest!

  d.  3/2r+2c ≤ 10

Step-by-step explanation:

The amount of flour Molly needs for r batches of oatmeal raisin cookies is ...

  3/2r

The amount of flour Molly needs for c batches of chocolate chip cookies is ...

  2c

The total amount of flour Molly can use for cookies cannot exceed the amount available, so ...

  3/2r + 2c ≤ 10

Comment on the question

The wording is a bit odd. It asks for the amount of flour available—after it tells you the amount available is 10 cups. (I might write that as f ≤ 10.) The answer choices clearly suggest that what is wanted is a representation of the possible mix of batches of cookies for which Molly could use the available flour. IMO, this is another instance of poor editing of math problem wording.

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
