Answer:
x = 1000
Step-by-step explanation:
Using the rule of logarithms
x = n , then
x =
Note that log x = x
Given
x = 3, then
x = 10³ = 1000
Let s and d represent the number of sit-ups Jerry does and the number of days Jerry has been doing them (not counting the first), respectively. The problem statement tells us
s = 16 + 2d
This is the equation that can be solved to find d.
_____
Here is its solution.
Since we want to find d (the number of days), we can subtract 16 and divide by 2.
s - 16 = 2d
(s - 16)/2 = d
d = (s/2) - 8
Example:
Today Jerry did 22 sit-ups. He has been doing them for ...
(22/2) - 8 = 11 - 8 = 3 . . . days
14r + 16 = 100
isolate the r: first subtract 16 from both sides
14r + 16 (-16) = 100 (-16)
how it looks now:
14r = 84
Than divide 14 from both sides to isolate the r
14r/14 = 84/14
how it looks now:
r = 6
Answer: r = 6

3/15 = x/4
cross multiply
15x = (4)(3)
15x = 12
x = 12/15
x = 4/5 <==
