The four consecutive odd integers are x, x+2, x+4, x+6
x+x+2+x+4+x+6=216
4x+12=216
4x=204
x=51
they are 51, 53, 55, 57
A. you can add the numbers anyway you like and it won't affect the sum
"We learned that the commutative property of addition tells us numbers can be added in any order and you will still get the same answer. The formula for this property is a + b = b + a. For example, adding 1 + 2 or 2 + 1 will give us the same answer according to the commutative property of addition"
The Answer is 25
2 is the change in x, and the change in y is 50.
50/2=25
68.40 divide 6 = 11.4
41.80 divided 4= 10.45
