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

16 green pepper. There are 4 times the amount of red pepper is the green pepper, do a trial. I started with 5 so if there are 5 red peppers, 5*4=20, 20 plus 5 is too much so try 4 next. 4*4=16, 16+4 is exactly 20 pepper

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
