Answer:
1. x = 12
2. x = 5
Step-by-step explanation:
1. -222 = -2x - 12x - 54
-222 = -14x - 54
-168 = -14x
x = 12
2. 154 = 2x + 12x + 84
154 = 14x + 84
70 = 14x
x = 5
The answer: x=857 and y=-401
Set up the two equations
X+2y=55
2x+y=1313
Solve the system of equations by elimination
2x+y=1313
-2x-4y=-110
Add each of the corresponding terms together
-3y=1203
Divide by -3
Y=-401
Plug y back into one of the original equations
X+2(-401)=55
X-802=55
X=857
Answer:
The distributive property
Step-by-step explanation:
The equation 3+7x
Answer: The annual flow of the Mississippi river would fit in the Atlantic ocean
times.
Step-by-step explanation:
Given: Volume of Atlantic Ocean=
cubic meters
Annual flow of Mississippi river =
cubic meters.
then, the number of times the annual flow of the Mississippi river would fit in the Atlantic ocean = 
![=\dfrac{3.1\times10^{17}}{6.3\times10^{11}}\ \ \=0.492063492063\times10^{17-11}\ \ [\dfrac{a^m}{a^n}=a^{m-n}]\\\\=0.492063492063\times10^6\approx4.92\times10^5](https://tex.z-dn.net/?f=%3D%5Cdfrac%7B3.1%5Ctimes10%5E%7B17%7D%7D%7B6.3%5Ctimes10%5E%7B11%7D%7D%5C%20%5C%20%5C%3D0.492063492063%5Ctimes10%5E%7B17-11%7D%5C%20%5C%20%5B%5Cdfrac%7Ba%5Em%7D%7Ba%5En%7D%3Da%5E%7Bm-n%7D%5D%5C%5C%5C%5C%3D0.492063492063%5Ctimes10%5E6%5Capprox4.92%5Ctimes10%5E5)
Hence, the annual flow of the Mississippi river would fit in the Atlantic ocean
times.

It would seem the only solution is 0, but

and the denominator of the fraction can't be equal zero, therefore there's no solution.
