Answer:
see below (I hope this helps!)
Step-by-step explanation:
Alternate exterior angles are congruent so we know that ∠2 ≅ ∠ 7. Vertical angles are also congruent so ∠7 ≅ ∠6. Consecutive interior angles are supplementary so we know that ∠6 and ∠4 are supplementary. Now, we can use the Transitive Property (this states that if a = b and b = c then a = c) to compare ∠2 and ∠4. In this case, a = ∠2, b = ∠7 and c = ∠6 so we know that ∠2 ≅ ∠6 and since ∠6 is supplementary to ∠4, we can use the Transitive Property again to conclude that ∠2 and ∠4 are supplementary.
Answers and Explanation:
So I'm not sure about this at all since you probably already know:
For number 9, the rule would be that it "Multiplies by -3" or however you would write that (I haven't done this in a while.) This is because 7×-3=-21, -21×-3 is 63, and so on.
For number 10, the rule would be "It Multiplies by 3" for the same reason.
Sorry that this probably wasn't helpful because I don't know too much about the terms.
Answer:
9
Step-by-step explanation:
The factors of 9 are: 1, 3, 9
The factors of 36 are: 1, 2, 3, 4, 6, 9, 12, 18, 36
The factors of 189 are: 1, 3, 7, 9, 21, 27, 63, 189
Then the greatest common factor is 9.
Glad I could help!!
Answer:
a. 8 minutes
b. 7.5 tasks
Step-by-step explanation:
of an hour is just 40 minutes.
Let's use a ratio:
minutes : tasks
40 : 5
8 : 1
20 : 2.5
60 : 7.5
a. 8 minutes
b. 7.5 tasks
2x+15 = 3x-25
2x-3x = -25 -15
-x = -40
x = 40
