What is the x value for the solution

lidiya [134]3 years ago

Hey there!

So, first, you need to rearrange the second equation so y is in front.

x+y=10

Subtract x.

y=10-x

Plug that in for y.

2x+3(10-x)=45

2x+30-3x= 45

Subtract 30 on both sides.

-x= 15

Divide by -1 on both sides.

x=-15.

I hope this helps!

2. Exactly two outcomes

3. Outcomes are independent of each other

4. Probability of all the outcomes remains constant from trial to trial.

Success in the given experiment is that the baby recovers fully.

Hospital is caring for 6 babies , n = 6

p = 0.20 ( Success )

q = 1 - 0.20 = 0.80 ( Not a success )

Leokris [45]
The thing is that every 4 years, the tree grows 6 inches, so that could be expressed as a ratio, 4/6. That also means that every two years, the tree grows 3 inches since it could be simplified to 2/3.

Svetlanka [38]
The total measure of the interior angles of each figure will be:

180 (n-2) = 180 (4 - 2) = 360

Now add all those angles and set them equal to 360.

41 + 133 + 86 + x = 360

x is the unknown angle.

260 + x = 360
x = 100

The missing angle that is Not labeled in any of the figure is 100°

Hope this helps :)
