Answer:
<u>t = t₀ - 3n</u>
Step-by-step explanation:
Let t be the temperature and t₀ be the initial temperature of the day
Let n be the number of hours after the initial temperature ( t₀) was registered
Let -3 be the constant of change of temperature ( In 4 hours it went down 12 degrees)
Now, let's write down the expression that shows the temperature change each hour, this way:
t = t₀ - 3n
After 2 hours
t = t₀ - 3 * 2 = t₀ - 6
After 5 hours
t = t₀ - 3 * 5 = t₀ - 15
After 3 hours and 30 minutes
t = t₀ - 3 * 3.5 = t₀ - 10.5
Answer:
24
Step-by-step explanation:
If she did all 3of them today then you subtract a day from each one then it would look like this
5+4+15=24
Answer:

Answer:
Part 1) 
Part 2) 
Part 3) 
Part 4) 
Part 5) 
Step-by-step explanation:
Part 1) Write as a percent 0.00675
we know that
To write a number as a percent, multiply the number by 100
so
Part 2) Write as a percent 4 3/4
Convert mixed number to an improper fraction
we know that
To write a fraction as a percent, multiply the fraction by 100
Part 3) Write as a percent 2/25
we know that
To write a fraction as a percent, multiply the fraction by 100
Part 4) write as a fraction 335%
we know that
Simplify
Divide by 5 both numerator and denominator
Part 5) Write as a decimal 265%
we know that
The answer is: [C]: "<span>Equation 3" .

<u>Note</u>: Among the FOUR (4) equations in the answer choices; "Equation 3" is the only equation that does NOT contain an "exponent" (that is; an exponent other than the (implied exponent of "postive 1").
_________________________________________________________
Furthermore, "Equation 3" is written in "slope-intercept form" ; that is:
"y = mx + b" ; the form of a linear equation.
