For this case we must solve the following equation:
![\frac {x + 4} {3} = 2](https://tex.z-dn.net/?f=%5Cfrac%20%7Bx%20%2B%204%7D%20%7B3%7D%20%3D%202)
We follow the steps below:
Multiplying by 3 on both sides of the equation we have:
![x + 4 = 3 * 2\\x + 4 = 6](https://tex.z-dn.net/?f=x%20%2B%204%20%3D%203%20%2A%202%5C%5Cx%20%2B%204%20%3D%206)
Subtracting 4 from both sides of the equation:
![x = 6-4\\x = 2](https://tex.z-dn.net/?f=x%20%3D%206-4%5C%5Cx%20%3D%202)
Thus, the solution of the equation is![x = 2](https://tex.z-dn.net/?f=x%20%3D%202)
Answer:
![x = 2](https://tex.z-dn.net/?f=x%20%3D%202)
Answer:
The one that doesn't belong is the square root (the only irrational number in the list)
Step-by-step explanation:
The numbers;
50.1.....
50/2
and -50.1
are all rational numbers that can be written as a quotient of two integers.:
451/9 = 50.1111...
50/2
-501/10 = -50.1
The only one that cannot is the square root of 50 (it is an irrational number) since 50 is NOT a perfect square.
Four times a number plus twenty one
Answer:
I have:
33 - 3N/44 marbles
N = marbles of Nicole
Step-by-step explanation:
Nicole + me = 44 marbles
m = 44 - N
m = me
N = Nicole
if i lose 1/4 of my marbles
4/4 - 1/4 = 3/4
i have left:
3/4 of my marbles
then:
m = 3(44-N)/4
m = 3*44/4 + 3*-N/44
m = 33 - 3N/44
I have finally:
33 - 3N/44
