Amit solved the equation StartFraction 5 over 12 EndFraction = Negative StartFraction x over 420 EndFraction for x using the ste
ps shown below. What was Amit’s error?
StartFraction 5 over 12 EndFraction = Negative StartFraction x over 420 EndFraction. StartFraction 5 over 12 EndFraction (420) = Negative StartFraction x over 420 EndFraction (420). X = 175.
StartFraction 5 over 12 EndFraction = Negative StartFraction x over 420 EndFraction. StartFraction 5 over 12 EndFraction (420) = Negative StartFraction x over 420 EndFraction (420). X = 175.

Answer:
He did not work for 6 days
Step-by-step explanation:
Sam is hired for a 20-day period.
Let x be the no. of days he did not work
So, No. of days he worked = 20-x
he earns per working day = $60
So, he earns for (20-x) days = 60(20-x)
For each day that he does not work, $30 is subtracted from his earnings.
So, Amount deducted for x days = 30x
So, His earning for 20 days =
We are given that At the end of the 20-day period, he received $660
So,
So, he did not work for 6 days
So, Option C is true
Hi there! :)
Find the central angle using a ratio in regards to angle and circumference.
The radius is 27 units, so use the following equation to calculate circumference:
C = 2rπ
Therefore:
C = 2(27)π = 54π
Since we have the total circumference, we can write the following proportion:
Cross multiply:
54πx = 6480π
Divide both sides by 54π to isolate for x:
x = 120°
