Step-by-step explanation:

73. If 65% of x is 130, what is the value of x?<br>A. 84.5<br>B. 130<br>C. 165<br>D. 200<br>E. 260​
MrRissso [65]

Answer:

D) 200

Step-by-step explanation:

To find what x equals you have to use the expression:

is over of equals percent over 100

In this problem you are given the percent, 65%, and the is, 130.

So we are trying to find the of so you would substitute of with x.

So 130/x = 65/100

Now you would do Cross Product Property to find x.

So 130*100 = 13000

65*x = 65x

65x = 13000

65/65 = 1

13000/65 = 200

x = 200

So 65% of 200 is 130
