Answer:
x = 7/3
Step-by-step explanation:
<u>Given equation:</u>
To determine the value of "x", we need to isolate the x-variable and it's coefficient on one side of the equation. This can be done by subtracting 49 to both sides of the equation.
- ⇒ –9x² + 49 - 49 = 0 - 49
- ⇒ –9x² = -49
We can see that the negative sign in on both sides of the equation. Remove it by dividing -1 to both sides of the equation.
- ⇒ –9x² = -49
- ⇒ -9x²/-1 = -49/-1
- ⇒ 9x² = 49
Clearly, we can see that 9x² and 49 are perfect squares. Therefore,
Take square root both sides of the equation:
To determine the value of "x", we need to isolate it "completely". This can be done by dividing 3 to both sides of the equation
Therefore, the value of "x" must be 7/3.
Given : (5b - 9) - 3(8 - 26)
⇒ (5b - 9) - 3(-18)
⇒ (5b - 9) + 54
⇒ 5b - 9 + 54
⇒ 5b + 45
Answer:
y = x(4+z)+6
y-6 = x(4+z)
x=(y-6)/(4+z)

Answer:
Well I guess this is a math problem but the middle time would be: 6 hours and 30 minutes.
Step-by-step explanation:
Adding 6 hours to 2 pm makes 8:00 on the dot at night. Adding 30 minutes to 8:00 would be 8:30. There you have your answer.
