Answer:
4
Step-by-step explanation:
Since the base is the same, 3, you can just get rid of it using the principles of log. What you're left with is:
2x + 1 = x + 5
Now just solve for x:
2x - x = 5 - 1
x = 4
Answer:
Green heart is 2 and blue shape is 8.
Step-by-step explanation:
We know 1 purple drop equals 3.
So 3+3 = 6
The total weight is 16 so we can do 16-6 = 10
We have 10 left. Since we need the weight to be balanced the green heart must be 2.
Because then it would be 8 on 1 side (2 purples equals 6 and 1 heart equals 2, so 6+2=8) and 8 on the other side (8+8=16).
The answer will be
155 times 5 = 775
Answer:
option (b) is correct.
The value of 
is 0.
Step-by-step explanation:
Given: 
and 
We have to find the value of
Consider the given function
First evaluate value of function f(x) at x = 3 and 1 then substitute it in .
f(3) = 1 + 3 = 4
f(1) = 1 + 1 = 2
Substitute, we get
Solving further , we get,
Now evaluate at t = 0 , we get,
Thus, value of is 0.
Thus, option (b) is correct.
