Answer:
Kindly check explanation
Step-by-step explanation:
Given the model:
s = 10│x - 4│+ 50
s represents the sound level in decibels and x represents the number of measures of music played
To find x at s = 80
The equation becomes /
80 = 10│x - 4│+ 50
Subtract 50 from both sides of the equation
80 - 50 = 10 |x - 4| + 50 - 50
30 = 10 | x - 4 |
Divide both sides by 10
30/10 = 10|x - 4| / 10
3 = |x - 4|
|x - 4| is an absolute value expression
±3 = |x - 4|
x = 3 + 4 = 7
x = - 3 + 4 = 1
Answer:
Step-by-step explanation:
we know that
The simple interest formula is equal to
where
A is the Final Investment Value
P is the Principal amount of money to be invested
r is the rate of interest
t is Number of Time Periods
in this problem we have
substitute in the formula above
Answer:
x < 21.9
Step-by-step explanation:
Just follow the same rules as if you were solving for x
<u>14.2 + 15.5</u> + x < 51.6 = Combine like terms
<u>29.7</u> + x < 51.6 = Subtract 29.7 to isolate x
x < 21.9
