Answer 1

128/512 = 1/4

Answer 2

what is the sequence is geometric, what is the common ratio?
48, 46, 44, 42

Answer 3

46/48=23/24

Answer 4

yu divide any term by the one that comes before it

Answer 5

8x − 2 = y − 3
4x − y = -2

Answer 6

8x-y=-1
4x-y=-2

subtract both equations u get

4x=1 so x=1/4

substitute x=1/4 in any equation yu get
2-y=-1
so y = 3
