Answer:
I think the answer is monarchies(D).
Step-by-step explanation:
The solution for the below equation is required:
4x + 6 - x = 2x + 3
The work done by the Jermaine is presented below :
4x + 6 - x = 2x + 3
5x + 6 = 2x + 3
Instead of adding 4x with -1x to make it 3x , he added 4x with 1x to make it 5x.
So, the correct option is
Jermaine did make an error. He should have combined 4x and -1x to make 3x
3x + 6 = 2x + 3

After 200 years, 9.84 grams of Cesium would remain.
Let N represent the amount of substance after t years
The half-life of a cesium is 30 years., hence, this can be represented by exponential function:

where a is the initial value and b is the multiplier.
There were initially 1000g of the substance
a) The exponential model for this situation is:

b) After 200 years (t = 200), the amount of Cesium remaining is:

Hence after 200 years, 9.84 grams of Cesium would remain
