Answer:
x = 1
Step-by-step explanation:
5x^5 + 5 = 10
Start the solution by subtracting 5 from both sides:
5x^5 = 5
Dividing both sides by 5 yields x^5 = 1.
Taking the 5th root of both sides, we get x = 1
Divide -6 by -2. The answer is -3. Add the x. So the answer is -3x.
10 is greater because it equals 3.162...
Answer:
2x + 2.9 = 30.6
Step-by-step explanation:
We are to represent the unknown number that Mark thinks of with x
If Mark doubles this unknown number, he multiplies it by 2 and the unknown number becomes - 2x
He then adds 2.9
The equation becomes 2x + 2.9
The answer of the above equation is 30.6
This gives : 2x + 2.9 = 30.6
