14*3=42
42+42=84
9*3=27
27+27=54
252+84+54=390
The value missed is 1 min / 60 seconds
<h3>What is unit conversion?</h3>
Units is the conversion between different units of measurement for the same quantity, typically through multiplicative conversion factors.
To convert 720 seconds to hour,
First convert second to minutes divide by 60 and then again convert minutes to hour again divide by 60.
So,
720 seconds * ( 1 minutes / 60 seconds) * ( 1 hour / 60 minutes)
= 12 hours.

Answer: a = -5
Step-by-step explanation:
First, open up the brackets, and solve it
-12a -42 = -22 -8a. (-6 x 2a, and -6 x 7)
bring the -8a to the left side, so that all the a’s are together
-12a -42 + 8a = -22 (add -42 on both sides like we did with -8a)
-12a + 8a = -22 + 42
solve
-4a = 20
divide -4 on both sides
a = -5
Answer:
B (1,1) & (2,-1)
Step-by-step explanation:
This is the answer because if a line was drawn through these 2 points the slope would be the same as line QR so therefore the two would be parallel.
Hope this helps :)
