Answer:

-13

Step-by-step explanation:

Given that:

Average temperature for a period of 4 days = - 8

Average temperature for a 5 day period = - 9

Temperature on the 5th day:

(total temp for the 4 days + 5th day temperature) / 5 = - 9

Let 5th day temperature = x

Total temperature for the 4 days = 4 * - 8 = - 32

(-32 + x) / 5 = - 9

-32 + x = - 45

x = - 45 + 32

x = - 13

Does anyone know this? <br> Will mark brainliest !!!!
stich3 [128]

Answer:

x=4

y=4√5

Step-by-step explanation:

Set up 3 right triangles and mark their respective angles. The largest will have sides (in typical a,b,c[hypotenuse] order) y, z, and 10. The middle 8, x, and y. The smallest x,  2, and z.

Then since they are all similar triangles, using the midde and smaller triangles, set up the proportionin which both A sides when divided are equal to the B sides.

So 8/x = x/2

Cross multiply and get 16=x^2.

The  square root of 16 is 4, so x is 4.

Then using the larger and middle triangles, do the same for the A and C sides.

So y/8 = 10/y.

Cross multiply and get 80=y^2.

Find the square root of it, which since it doesn't have a perfect square, you use a calculator or the whatever theorem and get √4*4*5 or simply 4√5.

So x = 4 and y = 4√5

Solve for x.<br> -5/6x-1/9x=-102<br> x = ______?
kifflom [539]

Answer:x=1/108 is your answer

-5/6x-1/9x=-102

1/x(-5/6-1/9)=-102

1/x=-102/(-17/18)=-102×-18/17=108

x=1/108
