So what we are going to do is the next thing:Consider 18x-9>9 1. add 9 to both sides 2. divide both sides by the coefficient of x (that is 18 in this case) Now Consider 2x-4>-10 1. Then add 4 to both sides 2. divide both sides by the coefficient of x (that is 2 in this case) The final solution would be x < 1 Hope this can fit what you are looking for
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
