Answer: z = -7
Step-by-step explanation:
Simplify the equation so the Integer is on the right:
8 - 12z = 92
-12z + 8 = 92
Now subtract 8 from both sides:
-12z + 8 - 8 = 92 - 8
-12z = 84
Now divide both sides by 12 to get z by itself:
-12z/-12 = 84/-12
z = -7

Answer:
n = log(
)
Step-by-step explanation:
Take the logarithm of both sides of the equation to remove the variable from the exponent.
Answer:
(a) $60 | (b) $660
Step-by-step explanation:
We can use the simple interest formula for this:

<em>I = interest amount</em>
<em>P = principal amount</em>
<em>r = interest rate (decimal form)</em>
<em>t = time (years)</em>
<em />
First, change 5% into its decimal form:
5% ->
-> 0.05
Next, plug in the values into the equation:


<em>The interest earned is $60. To find the total balance, just add the $600 back.</em>

The total interest earned is $60 and the total is $660.
