Answer:
a d c
Step-by-step explanation:
Each one would be 5 minutes because 2 1/2 Times 4 = 10 minutes. You would have 20 minutes remaining so divide 20 by how many segments there are, which is 4 to get 5
31
This is simple. The tens digit has to be two less than the ones.
The numbers that fit this rule are...
20 31 42 53
Then, they have to be in between 25 and 50.
The numbers that fit this rule are...
31 and 42
Then, i has to be prime
31 is the only one that fits all three
20x+3
This shouldddd be the answer sorry if I’m wrong, but if you group all the x variables together they add up to twenty, then you just add “+3” being that it has no x and therefore must be put in some form of separate group!
