Answer:
log(2)
Step-by-step explanation:
In order to combine log(10) and log(5), you need to look at the sign that's combining them. In this example, it is a subtraction sign. When two logs are being subtracting from each other, it's the same as dividing the two. You would rewrite it like this:
log(10/5)
You would then solve 10/5, and get 2. You would rewrite the log as:
log(2)
Answer:
4 and 8
Step-by-step explanation:
Let 'a' represent one of the numbers. Then the other is 12-a, and their difference is ...
a - (12-a) = -4
2a = 8 . . . . add 12
a = 4 . . . . . divide by 2
12-a = 8 . . . . find the other number
The two numbers are 4 and 8.
You need to represent it as 2x + 10 = 50
