3.2 less days than 16 because each 25 is 5 than 16 divide by 5 is 3.2
In the equation
divide both sides by to get
Take the base-3/2 logarithm of both sides:
Alternatively, you can divide both sides by :
Then take the base-2/3 logarith of both sides to get
(Both answers are equivalent)
Answer:
Alvin: 49
Elga: 40
Step-by-step explanation:
- The equation is 89 = x + (x-9).
- Remove the parenthesis and combine the like terms. 89 = 2x - 9
- Add 9 on both sides. 98 = 2x
- Divide by 2 on both sides. x = 49
- 49 is the age of Alvin. (49-9) 40 is the age of Elga.
