Well, in the first one, 2 degrees below zero is -2 degrees, and then it says that it dropped 14 degrees, which means it dropped -14 degrees, so to know the total amount it dropped you would just have to add -2 plus -14 which is -16 degrees, so your answer for the first question would be the last answer, -16 degrees.
For the second question, just know that whenever a negative number is BY ITSELF in parentheses, that means it is used like a positive number in the equation. So (-12) automatically becomes 12. Now, since the problem is asking for a SUM, (the answer to an ADDITION problem; when you add instead of subtract), you would turn that minus symbol to a plus symbol, and add normally to get your final answer; 30 + 12 = 42. To check if this is correct, just type in <span>30 – (–12) to a calculator and you'll get the same answer! :D
Hope this helps! :3</span>

By the converse of the hinge theorem, mC = mS. FALSE. EITHER ANGLE IS LARGER THAN THE OTHER
By the hinge theorem,TS > AC. FALSE. CONGRUENT SIDES BASED ON THE GIVEN IMAGE.
By the converse of the hinge theorem, mS > mC.the statement that is true
By the hinge theorem, BA = RT. FALSE. 3RD SIDE OF EITHER TRIANGLE WILL BE LONGER THAN THE OTHER.
Answer:
cost = 1.35n
$33.75 for 25 songs
Step-by-step explanation:
Based on the numbers given, the cost is proportional to the number of songs downloaded. The constant of proportionality is the cost of one song: 1.35.
cost = 1.35n
For 25 songs, ...
cost = 1.35·25 = 33.75 . . . . dollars
__
The equation is ...
cost = 1.35n
Answer:
The competition took 12.5 minutes.
Step-by-step explanation:
Let the time taken by Achilles to complete the competition is h hours.
Now, Achilles runs at a speed of 13 mph while the Turtle moves at a speed of 1 mph.
So, the competition was 13h miles long.
Now, Turtle will take h hours to complete h miles of the competition.
Now, given that (13h - h) = 2.5
⇒ 12h = 2.5
⇒ h = 0.208 hours.
⇒ h = 12.5 minutes.
Therefore, the competition took 12.5 minutes. (Answer)
