X = 1 is the correct answer.
Using the log properties, remember that Log(base2)2 = 1
3log(base2)2x = 3
divide both sides by 3
log(base 2)2x = 1
log(base2)2 = 1
1 * x = 1
x = 1
x^2 - 49 = 0
Add 49 to both sides:
x^2 = 49
Take the square root of both sides:
X = 7
Answer:
21kg
Step-by-step explanation:
We will do this.
11x - 12 = 7x
11x - 4x = 7x
4x = 12
4x/4 = 12/4
x = 3
3 x 7 = 21
