Step-by-step explanation:

We can use a ratio to solve

9 stars           x

---------    = -----------

2 hearts        4 hearts

Using cross products

9*4 = 2x

36 = 2x

Help I need a second opinion. Is my answer correct? See pic below.
nadya68 [22]

You're first one is correct, with the increase of Petroleum being the most at 3.4%


However, the second one is incorrect, because you are finding the percentage increase, or 12.7 - 9.3 = 3.4%


So the second one is 3.4



hope this helps

PLEASE HELP ASAP! DUE SOON PLEASE SHOW YOUR WORK
viktelen [127]

Answer:

So for the first one the first ting u have to do is FLIP the equation so---> X-12=y

Then you have to add 12 to BOTH sides----> x-12+12=y+12

<u><em>So your answer for X ----> x=y+12</em></u>

<u><em>For Y on the first equation it is--->y=x-12</em></u>      (Just flipped and the sign changed)

For the second equation we are gonna solve for Y first.

The first thing u want to do is divide both sides by -3 so it will look like this

-3y/-3    =   2x/+36/-3

<u><em>So Y will equal-----> -2/3x- 12</em></u>

Now we are going to do the X part

So fist FLIP the equation---->      2x+36=  -3y

The add -36 to both sides-----> 2x+36+-36=-3y+-36

Last step you have to divide both sides by 2

So that would be----> 2x/2= -3y-3

<u><em>Your final result will be----> x=-3/2y-18</em></u>

I hope this helped you out (:::::::
