Step-by-step explanation:
(x−1)²−9=0
(x-1)²= 9
x-1 = ±√9
x-1 = ±3
x = 1-3=-2 or x=1+3=4
the solution = {-2,4}
Represent Age of Time Traveler =========> X
Solve:
x = 3(x - 20 )
Step 1: Simplify Both sides of equation:
x = 3(x - 20 )
x = (3) (x) + (3) ( - 20 ) (Distribute ):
x = 3x + - 60
x = 3x - 60
Step 2: Subtract 3x from both sides:
x - 3x = 3x - 60 - 3x
- 2x = - 60
Step 3: Divide both sides by -2:
- 2x / - 2 = - 60 / - 2
x = 30
Answer: Our Time Traveler is 30 years old.
Hope that helps : )
(4logs/2hours) = (x logs/8 hours)
(4/2) = x/8)
Cross multiplication gets you:
(4)(8) = (2)x
32 = 2x
x = 16
16 logs
Answer: 9/24
Step-by-step explanation: multiply 8 by 3 to get 24 so you would multiply the 3 by 3 to get 9 as the numerator.
