Answer: x = -1
Step-by-step explanation:
The problem is asking you the sum (+) of 3 times of a unknown number (let the unknown number be x) and 7, as in 3x + 7
According to the problem this expression is equal to 4,
3x + 7 = 4
1. Subtract 7 from both sides
3x = -3
2. Divide 3 on both sides
x = -1
Your final answer would be negative 1
To solve this, first make an equation:
![750(x)^{12}=1500](https://tex.z-dn.net/?f=750%28x%29%5E%7B12%7D%3D1500%20)
After you solve this, you get x = 1.0399, but we have to subtract 1 so we get 0.0399 which is
3.99%
Answer:
Lo mcm es 252.
Step-by-step explanation:
El objetivo de esta queston es encontrar el mínimo multiplo comun de estes tres numeros.
Para eso, factoramos estes numeros en valores primos, e despues multiplicamos estos factores.
12 21 63
12 - 21 - 63|2
6 - 21 - 63|2
3 - 21 - 63|3
1 - 7 - 21|3
1 - 7 - 7|7
1 - 1 - 1
2*2*3*3*7 = 252
Lo mcm es 252.
