"a number x is 125% of y. to complete y, the number x has to be multipled by a. 0.25 b. 0.60 c.0.75. d. 0.80 the right ans is 'd' anybody solve this question & tell me how comes the ans is 0.85

x=5

Step-by-step explanation:

So first you would write out the equation like this:

8x+50=90

Then to find x you would have to do the inverse to 'undo' the equation.

So first you would, instead of adding 50, you would have to take it away from 90.

Your equation will then look like this:

8x=40

Then, you need to divide 40 by 8 because when a number and letter is next to each other in algebra, it means times so then you would do the inverse again.

So, your answer will be x=5

Hope this helps :)
