Please see below solution:
Let x = number of books that Bryan reads2x for amanda = Amanda 3x - 4 for Colin Amanda = 5/8(Bryan + Colin)2x = 5/8(x+3x-4)2x = 5/8(4x-4)
[16x = 5(4x-4)]816x = 20x - 20Subtract 20x from each side-4x =-20-4x/-4= -20/-4 divide -4 to eliminate the -4 in -4xx = 5
Therefore:
Bryan reads 5 books a month.
Since Amanda reads twice as many books a Bryan read so Amanda 10 books a month.
And Colin 11 books a month. 3(5) - 4 = 11
Luis’ sample would be the most random, because not everyone in the cafeteria might check out books from the library, but since everyone Samantha surveyed was in the library already, most of the people she surveyed would be more consistent in their responses.
Answer:
64(64-6) = 3712
Step-by-step explanation:
64(64 -6)
64-6 = 58
64(58) = 3712
C is 12 and x is 3 and that would be your variables
Answer:
-0.375
Step-by-step explanation:
To find which is closest, convert each to decimals.
-3/8 = -0.375
and
-0.45
Since the average is 0, -0.375 is closer.
