Mr. Lester needs less than 12 cup but more than 13 cup of flour to make a sauce. Which of the following could be the amount of flour that he needs? 1/4 cup
7/12 cup
3/8 cup
7/8 cup

3/8 cup

Step-by-step explanation:

To figure out how many cups of flour he could use, let's convert the fractions into decimals. We are told that amount he needs is less than 1/2 and more than 1/3.

1/2 = 0.50

1/3 = 0.33

So, the amount he needs is less than 0.50 and more than 0.33. Now let's convert the answer choices to decimal form:

1/4 = 0.25

7/12 = 0.58

3/8 = 0.38

7/8 = 0.88

The only answer choice that is less than 0.50 but greater than 0.33 is 0.38, or 3/8 cup.

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
