Answer is c (there is not a enough info given)
44 divided by twelve is four so you have to times 2. 1/2 by four so you will have enough so the answer is 10 cups of flour
Commutative says you can add or multiply in any order
basically goes like this
a+b=b+a or
ab=ba
so what we need is something where the order change, nothing else
first one: (4+3)+x=(3+4)+x, the order changed, correct
2nd
ab=ba, this is not addition
3rd
r+(s+t)=(r+s)+t this is associative property
4th
n+0=n
this is zero addition property
answer is first one
Through a geometric proof, 2(55x-1) = 107x+1
110x-2=107x+1
3x=3
x=1
Angle DEF is 54 degrees.
X=60 and y=20
x and y can be many things that answers the question to 120
