Answer:
x = -5 or x = -4/3
Step-by-step explanation:
First possibility.
|2x − 1| = |4x + 9|
2x - 1 = 4x + 9
2x - 4x = 9 + 1
-2x = 10
x = 10/-2
x = -5
Second possibility.
2x - 1 = - (4x+9)
2x - 1 = -4x - 9
2x + 4x = -9 + 1
6x = -8
x = -8/6
x = -4/3
Part A
The number of walking planks is given by the series
5, 9, 13, ...,
This is an arithmetic series with
a = 5, the first term
d = 4, the common difference
On the n-th day, the number of walking planks is
Answer:
Part B
On the 12-th day, the number of walking planks is
Answer: A. 49
Answer:
14.5 hours/14 hours 30 minutes
Step-by-step explanation:
- The distance between the two cities is 7.25•100=725 because you multiply the scale distance by the scale.
- The number hours is 725/50=14.5 hours because you divide the distance by 50 (the miles per hour).
Answer:
Places in binary coding
1 - 2 - 4 - 8 - 16 - 32 - 64 - 128 - 256 - 512 - 1024 - 2048
2483 - 2048 = 435 there is 1 in the 2048 position
435 - 256 = 179 there is 1 in the 256 position
179 - 128 = 51 there is 1 in the 128 position
51 - 32 = 19 there is 1 in the 32 position
19 - 16 = 3 there is 1 in the 16 position
3 - 2 = 1 there is 1 in the 2 position
1 - 1 = 0 there is 1 in the 1 position
10011011 0011 would be the binary result
Check:
2048 + 0 + 0 + 256 + 128 + 0 + 32 + 16 + 0 + 0 + 2 + 1 = 2483
