Answer:
B. If x isn’t divisible by 4, then x isn’t divisible by 2.
Step-by-step explanation:
contra positive statement is obtained by interchanging the hypotheses and conclusion of the inverse statement.
Here given that statement p is
If x is divisible by 4, then x is divisible by 2.
To write contrapositive of p, first we interchange the hypothesis.
Then it would look like
If x is divisible by 2, then x is divisible by 4.
Now we make conclusion as negative. i.e.
If x is not divisible by 4, then x is not divisible by 2.
This is the contra positive statement of p
Hence option B is right.
Vertical angles i believe is the right answer to this problem
Answer:
Step-by-step explanation:
Since there are 4 cities, there are (4-1)! = 6 possible routes. Half of those are the reverse of the other half, so there are 6/2 = 3 different possible routes. All of those are listed among the answer choices, along with their cost. All you need to do is choose the answer with the lowest cost:
ACDBA, $900
__
At $960, the other two routes are higher cost.
Answer:
4°
Step-by-step explanation:
All the angles in a triangle add together to equal 180°. We know there are three angles of 20° so let's subtract this.
20° × 3 = 60°
180° - 60° = 120°
Now well divide 120° up among the three angles.
120° ÷ 3 = 40°
Now we know the angles are 40° + 20°, but we need to find the value of x, so divide 40° by 10
40° ÷ 10 = 4°
x = 4°
