Answer:
The number of Apples did Ravi have at first is 125 .
Step-by-step explanation:
Let the number of Apples did Ravi have at first = x
The Apples which is sold by Ravi = 
of x
So, remainder now = x - of x = 
of x
The apples given to his friend = 
of x
I.e The apples given to his friend = 
of x
Now, The remaining Apples did Ravi have = 50
∴ According to question
of x - of x = 60
Or, 
of x = 60
Or, 
of x = 60
∴ x = 
= 125
Hence The number of Apples did Ravi have at first is 125 . Answer
The original answer should be 48/100.
Reduced is 24/50
Even more is 12/25
Your answer is 12/25
Must be
(c) 12.11.10
Or
(d) 12
Answer:
+ 1
Step-by-step explanation:
Given
x² + 2x = 9
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(1)x + 1² = 9 + 1²
(x + 1)² = 10
k = 5
the equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k ) are the coordinates of the vertex and a is a multiplier
To obtain this form use the method of completing the square
Since the coefficient of the x² term is 1 then
add/ subtract (half the coefficient of the x-term )² to x² - 6x
f(x) = x² + 2(- 3)x + 9 - 9 + 14 = (x - 3)² + 5 → k = 5
