Let first number be 6x and the second number is 7x. According to the question, => (6x + 9)/(7x + 9) = 9/10 => 60x + 90 = 63x + 81 => x = 3 Required difference = 7x – 6x = x = 3
Find the value of 'a' and 'b' which satisfy the following equations:
9a + 7b = 30
4a - 5b = 62
I. 2p2 + 5p + 2 = 0 II. 2q2 + 11 q + 14 = 0
I. 8/(√x) + 6/(√x) = √x
II. y ³- (14)7/2 /(√y) = 0
If x - √3 y = 8 Find the slope in angle?
I. p² - 365 = 364
II. q - √ 529 = √ 169
