Replace 5 with the number you are using. 5.00 5%
You substitute in an expression by filling in the desired and accustomed unknown value to the value you're trying to find. An example below can better elaborate what I want to say above. In the equation below, 7 - 2n = 5 the unknown is represented by n moreover, the equation suggest to find the missing to make it equilateral on both sides.
In mathematical expression, the equation then becomes 7 - 2n = 5
The next procedure is to find the unknown.
1. 7 - 2n = 5
2. -2n = 5 - 7
3. -2n = -2
4. n = -2/-2
5. n = 1
Check:
Substitute n = 1
7 - 2 (1) = 5
7-2 = 5
5=5
We have that
1/16 = 64<span>^x
applying log both sides
log(1/16)=log(</span>64^x)
log 1-log16=x*log64
-log 16=x*log 64
divide by log 64 both sides
x=-log 16/log 64
log 16=log 2^4-----> 4*log 2
log 64=log 2^6-----> 6*log 2
-log 16/log 64=(-4*log 2)/(6*log 2)-----> -4/6------> -2/3
the answer is
x=-2/3
Answer:
4
Step-by-step explanation:
add the numbers.
3+7+4+2= 16
then divide the answer by how much there is.
16 // 4= 4
//= divide
hope this helps
