Answer:
![43/100](https://tex.z-dn.net/?f=43%2F100)
Step-by-step explanation:
First, make both of the denominators into 100.
Then, 3/10 would be 30/100.
Finally, you can add them to get 43/100.
Step-by-step explanation:
x−7(x−2)=10x+9−x
Step 1: Simplify both sides of the equation.
x−7(x−2)=10x+9−x
x+(−7)(x)+(−7)(−2)=10x+9+−x(Distribute)
x+−7x+14=10x+9+−x
(x+−7x)+(14)=(10x+−x)+(9)(Combine Like Terms)
−6x+14=9x+9
−6x+14=9x+9
Step 2: Subtract 9x from both sides.
−6x+14−9x=9x+9−9x
−15x+14=9
Step 3: Subtract 14 from both sides.
−15x+14−14=9−14
−15x=−5
Step 4: Divide both sides by -15.
−15x−15=−5−15
x=13

A.
![\sf -1200 + 2.5N = -5000+1.6N](https://tex.z-dn.net/?f=%5Csf%20-1200%20%2B%202.5N%20%3D%20-5000%2B1.6N)
![\sf 2.5N - 1.6N = -5000 + 1200](https://tex.z-dn.net/?f=%5Csf%202.5N%20-%201.6N%20%3D%20-5000%20%2B%201200)
![\sf 0.9N = -3800](https://tex.z-dn.net/?f=%5Csf%200.9N%20%3D%20-3800)
![\sf N = \frac{-3800}{0.9}](https://tex.z-dn.net/?f=%5Csf%20N%20%3D%20%5Cfrac%7B-3800%7D%7B0.9%7D)
![\sf N = -4222\frac{2}{9}](https://tex.z-dn.net/?f=%5Csf%20N%20%3D%20-4222%5Cfrac%7B2%7D%7B9%7D)
![\sf N = -4222.222...](https://tex.z-dn.net/?f=%5Csf%20N%20%3D%20-4222.222...)
Find P:
![\sf P = -5000+1.6(4222.222)](https://tex.z-dn.net/?f=%5Csf%20P%20%3D%20%20-5000%2B1.6%284222.222%29)
![\sf P = -11755.55...](https://tex.z-dn.net/?f=%5Csf%20P%20%3D%20-11755.55...)
B.
As the number continues and is endless, it is an approximate solution.
