73. If 65% of x is 130, what is the value of x? A. 84.5 B. 130 C. 165 D. 200 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

One hour on earth is four hours on planet S.

Andreas93 [3]

Answer:

The answer is 60 hours.

Step-by-step explanation:

We could use proportions to solve.

$\frac{1 \: hour \: on \: earth}{4hours \: on \: planet \: s} = \frac{x}{240hours \: on \: planet \: s}$

$4 \times x = 4x \\ 1 \times 240 = 240$

$\frac{4x}{4} = \frac{240}{4} \\ x = 60$
