I think its 3/6 * 78 time = 39
Answer : 39 times
Hopefully it’s correct :)
Answer:
The required number is 130
Step-by-step explanation:
Let the number be x
Given :-. 50% of a number ( 50% of x ) is added to the number ( x ) the result is 195.
x = 130 !

2 2/3 ÷ 2/4= 1/3
The answer is 1/3.
Well the exact form is 1/3138428376721
and in decimal form it's 3.18630817 • 10 ^-13
Solve for x over the real numbers:
x^4 - 17 x^2 + 16 = 0
Substitute y = x^2:
y^2 - 17 y + 16 = 0
The left hand side factors into a product with two terms:
(y - 16) (y - 1) = 0
Split into two equations:
y - 16 = 0 or y - 1 = 0
Add 16 to both sides:
y = 16 or y - 1 = 0
Substitute back for y = x^2:
x^2 = 16 or y - 1 = 0
Take the square root of both sides:
x = 4 or x = -4 or y - 1 = 0
Add 1 to both sides:
x = 4 or x = -4 or y = 1
Substitute back for y = x^2:
x = 4 or x = -4 or x^2 = 1
Take the square root of both sides:
Answer: x = 4 or x = -4 or x = 1 or x = -1
