Unit rate for hours to miles
5 ( f + 4) = 4 ( f - 6)
f = -44
Hope this helps :)
Answer:
The answer is -44
Step-by-step explanation:
First, you use distributive property on each side.
5xf + 5x4 = 4xf-4x6
5f+20=4f-24
Then you subttract 5f to both sides of the equation.
5f+20=4f-24
-5f -5f
20=-1f-24
Next, you add 24 to both sides of the equation.
20=-1f-24
+24 +24
44=-1f
Finally, you divide -1f from each side of the equation.
44=-1f
/-1f /-1f
Your final answer should be -44=f
or f = -44
A linear function can be used to estimate the decrease in snowfall measured since 1920. The decrease in the annual snowfall has been on average 0.24 inches per year. Let x represent the number of years since 1920, when the measurements began, and let y represent the annual snowfall. The initial measurement in 1920 was 48.6 inches. Using the average change and initial measurement, which is the best estimate of the annual snowfall in the 78th year after records were kept? Round to the nearest hundredth.
Answer:
29.88 inches
Step-by-step explanation:
Equation of a line is given in the form
Where
m is the slope [rate of change, here, rate of decrease]
c is the y-intercept [at 1920, the snowfall]
From the problem, we see that snowfall decreases by 0.24 inches per year, that will make the slope (m) to be -0.24
Also, at 1920, the initial measurement was 48.6 inches of snow, that is the y-intercept (b). Thus, we can write the equation of this line as:
y = mx + b
y = -0.24 x +48.6
To find annual snowfall, 78th year after 1920, we simply plug in 78 into "x" of the equation just found. So:
y = -0.24(78) + 48.6 = 29.88 inches

29.88 inches

The temperature at a mountain base camp was −3 degrees Celsius on Monday. Tuesday morning, the temperature was 2 degrees Celsius lower than what it was on Monday. By Tuesday evening, the temperature was 4 degrees Celsius lower than what it was that morning. What was the temperature at the base camp Tuesday evening?
−9 degrees Celsius
−6 degrees Celsius
−5 degrees Celsius
−1 degree Celsius
Answer: -9 degrees Celsius
Step-by-step explanation: You subtract two degrees from -3 and get -5 (-3-2=-5). Then, you subtract 4 degrees from -5 and get the answer of -9 degrees Celsius.

A. 3x5 is 15! However since one of the number is a negetive, we must add a negetive sign to the 15, making it -15!
Remember this: A negetive number times a negetive number is a posititve number, but a negetive number times a positive number is a negetive!
B. 5+-5 is equal to 0, so 3x0 is 0!
C. No matter which way you mutliply it, whether it's -5x3 or 3x-5, the answer will always be -15! (-5)x(3+-3) is: 3+ -3 is 0, so -5 times 0 is the same thing as 5x0, which is still 0!
D. Like I said before, a negetive times a negetive is a positive, so -3x-5 is the same as saying 3x5, which is 15!

Answer: The distance in kilometers is equal to the distance in miles multiplied by 1.609344. Since one mile is equal to 1.609344 kilometers, that's the conversion ratio used in the formula. So 5 kilometers is approximately 3.1 miles
Answer: 3.10685
Step-by-step explanation:
Since 1 kilometer is equal to 0.62137 miles, and we have 5 kilometers, we simply multiply 5 by 0.62137 to convert 5 kilometers to miles.

Answer: 4,-4
Step-by-step explanation:
Your teacher shouldve given you a table on how to change the x,y depending on degrees but I Doubt you go to school like we did in middle school.So what you need to do is figure out the degrees.It is 90 minutes every 15 minutes and you need to find 30 minutes which means its times 2 which gives you 180 degrees.When a coordinate rotates 180 degrees the rule is -x,-y so that will change your x and y giving you your answer.

Determine if the given value makes the equation true or false. For x3 – 8 = 15, if x = 69
Answer:
(69)(3)−8 = 15
199≠15
False
Step-by-step explanation:
hope it helps, 69(3) is already bigger than 15, then -8 makes it 199, which is definitely not equal to 15.
Answer:
False
Step-by-step explanation:
69 * 3 =207
207 - 8 = 199
x3 - 8 = 199 for x = 69

Norah bought a guitar that was on sale for 15% off the regular price of $200. The total cost included 8% sales tax. What was the total cost?
A)$186.00
B)$183.60
C)$178.00
D)$176.80
A percentage is a number or ratio that represents a fraction of 100.
The total cost of the guitar including sales tax and the offer discount is $186.
What is percentage?A percentage is a number or ratio that represents a fraction of 100.
We have,
The regular price of the guitar = $200
Sales tax = 8%
Cost of sales tax = 8/100 x 200 = $16
Offer rate = 15%
Offer = 15/100 x 200 = $30
The total cost of the guitar:
= (200 - 30) + 16
= 170 + 16
= $186
Thus,
The total cost of the guitar including sales tax and the offer discount is $186.
Option A is the correct answer.

HELP I CANT DO MATH PLEASE
Answer:
A' : (-5, -8)
B' : (-5, -1)
C' : (2, -1)
Step-by-step explanation:
A is (-5, 8), B is (-5, 1), C is (2, 1), and we want to find the points after we reflect the triangle over x.
The first thing to remember is that when points are written like (x, y), the first number, x, is how many units you go right or left and the second number, y, is how many units you go up or down. The second thing to keep in mind is that the x-axis is the horizontal one that runs from left to right.
Now, just think about the information we have: if we want to flip a point like (-5, 8) over the x-axis, all we have to do is make the 8 negative. This is because the 8 is how far up the point is, so to make it flip down over the x-axis, we just change the sign. The -5 does NOT change because it's the x-value, which is how far right/left the point is. Does that make sense?
If we do this for the other two, (-5, 1) becomes (-5, -1) and (2, 1) becomes (2, -1).
(The apostrophe-like symbol the problem uses--like A', B', C'--just denotes that those are the resulting points after the reflection.)
