Answer:
no..........................
<span>The unit rate of 15 degrees in 2 hours.
It says here that in 2 hours, there are 15 degrees.
So we need to find the unit rate of this given situation per hours.
There are 2 hours
so you'll divide 2 by 15 to get the unit rate of the given situation
15 divided by two is 7.5
So the unit rate would be 7.5 degrees per hour.</span>
Answer:
There are 26 investors which contributed 6,000
And 34 investors which contributed 3,000
Step-by-step explanation:
You need to set up a two equation problem
![\left \{ {{258,000=6,000y+3,000x} \atop {60=y+x}} \right.](https://tex.z-dn.net/?f=%5Cleft%20%5C%7B%20%7B%7B258%2C000%3D6%2C000y%2B3%2C000x%7D%20%5Catop%20%7B60%3Dy%2Bx%7D%7D%20%5Cright.)
Now you have to clear "x" or "y" from the second equation:
![y = 60 - x](https://tex.z-dn.net/?f=y%20%3D%2060%20-%20x)
And replace on the first equation:
![258,000 = 6,000 (60 - x) + 3,000x\\258,000 = 360,000 - 6,000x + 3,000x\\3,000x = 360,000 - 258,000\\x = 102,000/3,000\\x = 34](https://tex.z-dn.net/?f=258%2C000%20%3D%206%2C000%20%2860%20-%20x%29%20%2B%203%2C000x%5C%5C258%2C000%20%3D%20360%2C000%20-%206%2C000x%20%2B%203%2C000x%5C%5C3%2C000x%20%3D%20360%2C000%20-%20258%2C000%5C%5Cx%20%3D%20102%2C000%2F3%2C000%5C%5Cx%20%3D%2034)
And now you use this "x" vale on the second equation
![60 = y + x\\60 = y + 34\\60 - 34 = y\\y = 26](https://tex.z-dn.net/?f=60%20%3D%20y%20%2B%20x%5C%5C60%20%3D%20y%20%2B%2034%5C%5C60%20-%2034%20%3D%20y%5C%5Cy%20%3D%2026)
There are 26 investors which contributed 6,000
And 34 investors which contributed 3,000
First, you have to make it into a mixed number : - 7 7/12. Since -7 7/12 can't be simplified anymore, it's the final answer
Step-by-step explanation:
X+100=180(linear pair)
X=180-100
X=80
30+y+x=180(sum of angle of triangle)
Y=180-110
Y=70
