Answer:
100 - 6x = 27
Step-by-step explanation:
32.725 is greater than 32.375

Call the number of hardcover and paperback books, h and p.
Thus
h + p = 8 and the value equation is
4h + 2p = 26
Now multiply the top one by four and subtract from the second one...we get
4h + 2p = 26
-(4h + 4p = 32)
----------------
-2p = -6
p = 3 so that
h = 5 x + y = 8, (1)
4x + 2y = 26, (2)
where x and y are the numbers of hardcover and softcover books respectively.
To solve, multiply the equation (1) by 2 (both sides) and then distract it from the equation (2). You will get
4x - 2x = 26 - 16, or
2x = 10, or x = 5 - the number of hardcover books purchased.
Then from the equation (1) you get y = 3.
Check. 4*x + 2*3 = 4*5 + 2*3 = 26. OK.
Answer:
choose B. 54 meters/second, it is closest to my calculation of 55 meters/sec
Step-by-step explanation:
To find average speed between 3 and 8 seconds, find the total distance traveled during that time.
650 meters at 3 seconds
to 375 meters at 8 seconds
then average speed = ( 650 - 375 ) / (8 - 3) = 275 /5 = 55 meters /sec
