Meredith picked 4 times as many green peppers as red peppers. if she picked a total of 20 peppers how many green peppers did she pick/

She picked 4 red peppers, and 16 green peppers.

Step-by-step explanation:

The best way to solve this is by setting up an equation. You can set it up as so: 20=x=4x. X would represent the number of red peppers she picked, since the amount of red peppers is and elaboration of how many green peppers there are (there are 4 times as many green peppers). Then you solve. You add like terms to get 20=5x, then divide both sides by 5. This leaves you with 4 red peppers. Then multiply 4 by 4 to get the amount of green peppers, in this case 16. Lastly add the 2 numbers gotten and see if they = 20 to check your answer.

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
