Answer:
a. 2n = 3n − 12, 12
Step-by-step explanation:
Let the number be represented by n.
Then 2 times the number is 2*n = 2n
3 times the number = 3*n = 3n
12 minus 3 times the number is 3n-12
It is given that 2 times the number is the same as 12 minus 3 times the number.
Expressing this equation form:
![\[2n=3n-12\]](https://tex.z-dn.net/?f=%5C%5B2n%3D3n-12%5C%5D)
Solving the equation,
![\[3n-2n=12\]](https://tex.z-dn.net/?f=%5C%5B3n-2n%3D12%5C%5D)
![\[=> n=12\]](https://tex.z-dn.net/?f=%5C%5B%3D%3E%20n%3D12%5C%5D)
Hence the required number is 12.
Answer:
a. The number of people that receive the text in the fourth round are 10³ people
b. The total number of people that receive the text are 1.1111 × 10⁴ people
Step-by-step explanation:
a. The given information are;
The number of people the text is sent to in the first round = 1
In the second round, the number of people the text is sent to by people in the first round = 10
In the third round, the number people the text is sent to by the 10 people in the second round = 10 × 10 = 100 people = 10² people
In the fourth round, the number of people the text is sent to by the people in the third round = 100 × 10 = 1000 people = 10³ people
The number of people that receive the text in the fourth round = 10³ people
b. In the fifth round, the number of people, the people in the fourth round send the text to = 1000 × 10 = 10000 people = 10⁴ people
The total number of people that receive the text = 1 + 10 + 10² + 10³ + 10⁴ people = 11111 people = 1.1111 × 10⁴ people
Is that the full question? I simplified it to 2x^2 -5x +18 when you plug x+3 in for the variable (x) in the expression. I’m honestly not sure when to go from there. Hope that helps with something. Sorry I couldn’t do more
