Y is inversely proportional to x. If y= 400 when x =2 find y when x= 200
o-na [289]

Answer:  4

<u>Step-by-step explanation:</u>

Inversely proportional means xy = k, where k is the constant of proportionality

First, find k when x = 2 and y = 400 ----> 2(400) = k   --> 800 = k

Then, find y when x = 200 (knowing that k = 800)

                                    200y = 800

                                           y = 4

maria [59]

Answer:

The missing side length is 6.

the following equation of ratios is true:

m        4

----- = -----

15       10

Cross-multiplying, we get:

10m = 60, or m = 60/10 = 6

The missing side length is 6.
