1.76
Subtract 2.5 to 3/4 by dividing 3 to 4 getting the answer of 1.76
Answer:


Step-by-step explanation:
Let x and y are the two positive real numbers
product of two numbers is 21


The sum of the two numbers is f(x) =x+y
Replace y with 21/x

we need to find smallest possible sum , so we take derivative using power rule

when sum is minimum then the derivative is equal to 0


multiply both sides by x^2


Take square root on both sides




Answer:
1
Step-by-step explanation:
Solve for x:8 (13 - 6 x) + 6 x = 0
8 (13 - 6 x) = 104 - 48 x:
6 x + 104 - 48 x = 0
6 x - 48 x = -42 x:
-42 x + 104 = 0
Subtract 104 from both sides:
(104 - 104) - 42 x = -104
104 - 104 = 0:
-42 x = -104
Divide both sides of -42 x = -104 by -42:
(-42 x)/(-42) = -104/(-42)
(-42)/(-42) = 1:
x = -104/(-42)
The gcd of 104 and -42 is 2, so -104/(-42) = -(2×52)/(2 (-21)) = 2/2×(-52)/(-21) = (-52)/(-21):
x = (-52)/-21
Multiply numerator and denominator of (-52)/(-21) by -1:
Answer: x = 52/21
75/100 is 3/4 in simplest form. To get this, we divide each number by the common multiple of 25, which gives us 3 and 4.
