They can be divided into
2 groups of 16
4 groups of 8
8 groups of 4
16 groups of 2
Your answer would be (b.) because -2+-3=-5
Hello!
You solve this like an algebraic equation
You first distribute the 4 and 2
4x - 20 = 2x - 20 + 2x
Combine like terms
4x - 20 = 4x - 20
subtract 4x from both sides
-20 = 0x - 20
Add 20 to both sides
0 = 0
This means that there are infinite solutions to the equation.
Hope this helps!
A, because you follow the numbers and just put "is to" and "as" in the middle.
