What is the value of x if 25x = 40?

  1. 5

  2. 8

  3. 15

  4. 20

The correct answer is: 8

To find the value of x in this equation, we need to isolate the variable by performing the opposite operation on both sides. Since 25 is being multiplied by x, we need to divide both sides by 25. This will cancel out the 25 on the left side and leave us with x on its own. When we divide 40 by 25, we get 1.6. Therefore, the value of x is 1.6 or fully simplified, 8/5. Therefore, option B is the correct answer. Option A is incorrect because if we plug in x = 5, we get 25(5) = 125, which does not equal 40. Option C is incorrect because if we plug in x = 15, we get 25(15) = 375, which also does not equal 40. Option D
