Connie is being difficult, please help me.

C

Step-by-step explanation:

1. Elimination

First we have to eliminate everything that is equal or below 20.

A. 12 + 21 = 33 > 20- Good

B. 16 + 9 = 25 > 20 - Good

C. 10 + 15 = 25> 20 - Good

D. 8 + 12 = 20 = 20 - Bad

So our other options are A, B, and C

2. Find the answers

So now we have to solve each one

A. 12 white marbles and 21 blue marbles = 12/21

12/21 = 2/3 - False

B. 16 white marbles and 9 blue marbles = 16/9

16/9 = 2/3 = False

C. 10 white marbles and 15 blue marbles

10/15 = 2/3 - True

C is the answer

C - Also connie is a little pee pee baby

Step-by-step explanation:

2x + 3x is more than 20

5x is more than 20

x is more than 4

answer is 2(5) white marbles and 3(5) blue marbles its number of white ones = 2/5 * 5n = 2n

number of blue ones = 3/5 * 5n = 3n

so 10 / 15 is the right answer

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.
