<span>the rate of decay each month can calculated using the following formula:
</span><span>
6%/year × 1 year/(12 months) = 0.5%/month
0.06 x 1/12 = 0.005/month
</span><span>So the 0.5% is the right answer.
I hope it helped.</span>
Answer:
x/2 + 21 = 36
First we get rid of constants to isolate the variable.
In order to do that we must do the inverse operation.
Inverse operation of addition is subtraction.
-21 -21(subtracting 21 from both sides, whatever we do to the left side we do it to the right side too)
x/2 = 15
inverse property of division is multiplication
x2 x2
X = 30
Answer:
multiply or simplify
Step-by-step explanation:
Answer:
Total monthly cost (x) = $39 + ($0.07/min)x
Step-by-step explanation:
The y-intercept is $39. The slope is ($0.07/minute)x, where x is the number of talk minutes. Thus:
Total monthly cost (x) = $39 + ($0.07/min)x, where x is the number of talk minutes.
