Answer:
260x = 170
x=170/260 * 100% = 65.4 %
Step-by-step explanation:
The answer is 25, 33. The difference between each consecutive number is 8.
Answer:
Option (2)
Step-by-step explanation:
Given equation is,
x⁴- 9x² + 8 = 0
Let x² = t
By substituting the value of x²= t in the equation,
t² - 9t + 8 = 0
t² - 8t - t + 8 = 0
t(t - 8) - 1(t - 8) = 0
(t - 1)(t - 8) = 0
(t - 1) = 0 ⇒ t = 1
(t - 8) = 0 ⇒ t = 8
Since, t = x²
x² = 1 ⇒ x = ±1
x² = 8 ⇒ x = ±2√2
Therefore, Option (2) will be the correct option.
Given:
Point G is the centroid of triangle ABC.
FG = x + 8 and AG = 6x - 4
To find:
The value of the variable x.
Solution:
Using rule of centroid:
Multiply by 3 on both sides, we get
⇒ 3(6x - 4) = 2(7x + 4)
⇒ 18x - 12 = 14x + 8
Subtract 14x from both sides.
⇒ 4x - 12 = 8
Add 12 on both sides.
⇒ 4x = 20
Divide by 4 on both sides.
⇒ x = 5
The value of x is 5.
