an adult has 4.94 x 10^13 cells = 49,400,000,000,000
49,400,000,000,000 - 26,000,000,000 = 49,374,000,000,000
scientific notation form : 4.9374 x 10^13
You said - 1/3 - 3/5 x = 1/2
Multiply each side by 3 :
- 1 - 9/5 x = 3/2
Multiply each side by 5 :
- 5 - 9x = 15/2
Multiply each side by 2 :
- 10 - 18x = 15
Add 10 to each side :
- 18x = 25
Divide each side by -18 :
<em>x = - 25/18</em>
or x = - 1 and 7/18 (same thing)
