-10x + 1 + 7x =37
-10x + 7x = 37 - 1
-2x = 36
X = 36 / -2
X = -18
Answer is x = -18
I think this is the answer

Answer:
2[-2y-4]
Step-by-step explanation:
2[-2y-4]=-4y-8
It would be 15-5=10 that is because you subtract q3-q1
Answer:
The population of the city in 2020 is 3,839,832
Step-by-step explanation:
Given:
Population at 2000 = 315,000
Rate at which the population increases = 2%
To Find:
The Population in the city after 2020 = ?
Solution:
The population in the city after 2020 can be found by using Exponential growth function.
Exponential growth occurs when a quantity increases by the same factor
Exponential growth function is ![y = a(1 + r)^t](https://tex.z-dn.net/?f=y%20%3D%20a%281%20%2B%20r%29%5Et)
Where
y is the final amount
a is the initial amount
r is the rate of increase
t is the time period.
Now substituting the values ,
In 2020 i.e., after 10 years
![y = 315000(1 + 2 \%)^{10}](https://tex.z-dn.net/?f=y%20%3D%20315000%281%20%2B%202%20%5C%25%29%5E%7B10%7D)
![y = 315000(1 + \frac{2}{100})^{10}](https://tex.z-dn.net/?f=y%20%3D%20315000%281%20%2B%20%5Cfrac%7B2%7D%7B100%7D%29%5E%7B10%7D)
![y = 315000(1 + 0.02)^{10}](https://tex.z-dn.net/?f=y%20%3D%20315000%281%20%2B%200.02%29%5E%7B10%7D)
![y = 315000(1.02)^{10}](https://tex.z-dn.net/?f=y%20%3D%20315000%281.02%29%5E%7B10%7D)
![y = 315000\times 1.218](https://tex.z-dn.net/?f=y%20%3D%20315000%5Ctimes%201.218)
y = 3,839,832.42
