42-9=33 so 43-?=33
43-33=10 so 43-10=33
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
Answer:
Step-by-step explanation:
Area of a triangle is A = height x base / 2
So plug in what you know.
42 = (14 x b)/2 get rid of the 2 by multiplying both sides by 2 which gives:
84 = 14 x b get rid of the 14 by dividing both sides by 14
b = 84/14
b=6 cm
Answer:
the last one
Step-by-step explanation:
its the last one because 1x3 is 3 so you need one with a 3, then 4x2 is 8 and theres half a side so its the last answer with half 3/4 on one side
