To start off with, DF=EG's reason is given, since you stated it was given.
Next, DE+EF = EF+FG's reason is because of the substitution property of equality. Think "if a = c, b = c, then a = b"
Lastly, DE = FG's reason is because of the Subtraction property of equality. If you subtract EF on one side, you must do it on the other side.

Answer:
An arithmetic sequence is a sequence of numbers in which the difference between the consecutive terms is constant.
Answer:



.
Step-by-step explanation:
We use the Venn diagram to calculate the desired probabilities.
Note that there are 6 possible results in the sample space
S = {1, 2, 3, 4, 5, 6}
Then note that in the region representing the intercept of A and B there are two possible values.
So

In the region that represents event A there are 4 possible outcomes {4, 5, 1, 2}
So

In the region that represents event B there are 3 possible outcomes {1, 2, 6}
So
.
Now


Answer:
Step-by-step explanation:
16.) 2/3
You add up the fractions and then reduce.
(5/12 + 3/12 = 8/12 = 2/3)
17.) No because if you add all the fractions together, you only get 7/8. This means the project is not complete yet.
