Answer:
15/2 or 7.5
Step-by-step explanation:
-4(x-1)+6x=2(17-x) PEDMAS
-4x+4+6x=34-2x combine terms
2x+4=34-2x subtract 4 and add 2x
4x=30 divide by 4
x=15/2

Let ŷ represent the profit (in thousands of dollars) for a certain company xx years after 1960. A statistician calculates a linear model
ŷ = -1.23 x + 16.07
Use the model to estimate the profit in 1965. Your answer should be in dollars, not thousands of dollars.
Answer:
![\=y =\$9.92](https://tex.z-dn.net/?f=%5C%3Dy%20%3D%5C%249.92)
Step-by-step explanation:
From the question we are told that:
Number of years ![N=1960-1965=>5years](https://tex.z-dn.net/?f=N%3D1960-1965%3D%3E5years)
Linear model ![\=y = -1.23 x + 16.07](https://tex.z-dn.net/?f=%5C%3Dy%20%3D%20-1.23%20x%20%2B%2016.07)
Therefore Inputting values into the model we have
![\=y = -1.23 (5) + 16.07](https://tex.z-dn.net/?f=%5C%3Dy%20%3D%20-1.23%20%285%29%20%2B%2016.07)
![\=y = -6.15+ 16.07](https://tex.z-dn.net/?f=%5C%3Dy%20%3D%20-6.15%2B%2016.07)
![\=y =\$9.92](https://tex.z-dn.net/?f=%5C%3Dy%20%3D%5C%249.92)
Step-by-step explanation:
Let the no. be x
![10\% \: of \: x = 39](https://tex.z-dn.net/?f=10%5C%25%20%5C%3A%20of%20%5C%3A%20x%20%3D%20%2039)
![\frac{10}{100} x = 39](https://tex.z-dn.net/?f=%20%5Cfrac%7B10%7D%7B100%7D%20x%20%3D%2039)
![\frac{1}{10} x = 39](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B10%7D%20x%20%3D%2039)
![x = 39 \times 10 = 390](https://tex.z-dn.net/?f=x%20%3D%2039%20%5Ctimes%2010%20%3D%20390)
Therefore , the no. is 390
6+4x=50
6-6+4x=50-6
4x=44
4x/4=44/4
x=11
The number is 11
