Answer:
5.5%
Step-by-step explanation:
The absolute error: 34.5-32.7=1.8
Percentage error: Relative error * 100%
To get the relative error, you can calculate it by (absolute error)/(actual value) or (max error)/(measured value)
Since you only have the absolute error and actual value, let's calculate it using that method.
(1.8/32.7)*100%=~5.5%
Answer:
x=4
Step-by-step explanation:
Because 4 to the power of 2 is 16.
Then, you subtract: 16x - 7x
Then, what you are going to see is 9x=3x+24
So, you subtract: 9x - 3x
Finally, you will have 6x=24... You divide: 24/6 and the answer is x=4.
Mentally your dividing the 12.50 by 10 and then thats 1/10 of it.
5x-8< -18
+8 on both sides
5x< -10
X< -2
