Question

29. If 1/2 is subtracted from a number and he difference is multiplied by 4 , the result is 5. what is the number ?

Answer 1

Step-by-step explanation:

Now:

Now: [x - 1/2] * 4 = 5

Now: [x - 1/2] * 4 = 5 4x - 1/2 * 4 = 5

Now: [x - 1/2] * 4 = 5 4x - 1/2 * 4 = 5 4x - 2 = 5

Now: [x - 1/2] * 4 = 5 4x - 1/2 * 4 = 5 4x - 2 = 5 4x = 5 + 2

Now: [x - 1/2] * 4 = 5 4x - 1/2 * 4 = 5 4x - 2 = 5 4x = 5 + 2 4x = 7

Now: [x - 1/2] * 4 = 5 4x - 1/2 * 4 = 5 4x - 2 = 5 4x = 5 + 2 4x = 7 x = 7/4

When 1/2 is subtracted from x which will give (x - 1/2) and the difference is multiplied with 4[x - 1/2]*4 to give 5. Therefore: When 1/2 is subtracted from 7/4 and the difference is multiplied by 4, the result is 5.
