-2x + 6 + 22 = -2x + 28
if the rectangle is 3 wide, then u subtract 3 twice from the perimeter 28. then you divide by 2 to get the length of one side of the rectangle: 28-3= 25-3= 22/2= 11 or 28-6= 22 22/2=11 so the answer is 11
11 x 2= 22 x+x=2 22 divided by 2= 11 22+11= 33 33-5=28
28 is the answer. if 12 is 15% of a number ,the number is 80. 35% of 80 is 28
12It follows the pattern of subtract 4; divide by 3; multiply by 2.

The answer is 109. 21 + (1 x 28) = 49 22 + (2 x 28) = 78 25 + (3 x 28) = 109
The series is a sequence of three numbers, the second number is 3 greater than the first, and the third number is 5 greater than the second. (or 8 greater than the first) 20 + 3 = 23 : 23 + 5 = 28 14 + 3 = 17 : 17 + 5 = 22 11 + 3 = 14........is therefore the next number in the sequence.
