Mary = M Chris = C
M = 3C-4
M-3=C+9 --> M=C+12
3C-4=C+12
2C=16
C=8
M=3C-4 --> C=8
M=3(8)-4
M=24-4
M=20
Mary is 20, and Chris is 8
20% we're caffeinated because out of 50 20% of 50 is 10
Answer:
This function s a linear relationship because this function increases about a consistent slope. The equation is 2x+5, where 2 is the slope.

How does the story make you feel when you read it? This is the mood or
"atmosphere." Tone is closely related, but with more emphasis on the
writing. So if the words make you laugh but are overwhelmingly dark, the
tone is "sarcastic" or "sardonic" and the mood is "dark" and "funny."
Honestly, the terms are often interchangeable.
I don't know but this is all I know I'm sorry

It may help to draw a picture as you start planning this problem and draw a circle, showing a circle which represents the scale needle's range of motion 360 degrees around. The needle length will then be the radius of that circle.
We know that the needle rotated 68 degrees and are trying to find the distance it traveled in cm. To find out how far the needle traveled, we need to find the arc length - in this case, the distance between the needle's starting point and where it ended up after the oranges were placed on the scale on the circle.
There is a formula you can easily use to find the arc length
arc length = 2*

*r (

)
We need to input the radius, r into this formula, as well as the central angle measure c, which in this case is 68 degrees.

If you multiply the above formula components all together using a calculator, you will get ~18.99. (When rounded to the second decimal place.)
So, the answer is around 19 cm. (Your answer may vary depending on how your teacher usually wants you to round answers.)
