Class IX If F = (9/5)C + 32, then the value of F if the value of C is 30 is 84 85 86 87 Linear equation in one variable is 2x = y y² = 3y + 5 4x - y = 5 4x - y = 5 The taxi fare in a city is as follows: For the first kilometer, the fare is Rs.8 and for the subsequent distance it is Rs.5 per kilometer. Taking the distance covered as ‘x’ km and total fare as Rs.y, write a linear equation for this information. y = 5x – 3 x = 5y – 3 y = 5x + 3 y = 5x + 4 The cost of 2 kg of apples and 1 kg of grapes on a day was found to be Rs.160. A linear equation in two variables to represent the above data is 2x + y = 160 x + 2y = 160 none of these. None of these The geometrical representation of 5x + 7 = 0 as an eqaution in one varibale is x = 7/2 x = -7/2 x = -2/7 x = -2/7 Do you really want to submit this quiz? Cancel Submit Quiz
