Answer:

47/45 = 1 2/45

Step-by-step explanation:

- If you would like a more in-depth explanation please let me know. Hope this helps!

- First you have to find a common denominator. This will be 45.

- Now, figure out what you multiply to get 45. For example...

4 = 12 + 7 = 35 (add these up)

15 45 9 45 It should equal 47/45 = 1 2/45.

If x varies directly with y and x = 3.5 when y = 14, find x when y = 18.

maks197457 [2]

Answer:

x = 4.5

Step-by-step explanation:

there's definitely other ways to solve this, but I used a proportion.

$\frac{3.5}{x} = \frac{14}{18}$

Then you can make this equation:

14x = 3.5 * 18

I solved for it and got 4.5 .
