Hello, the answer is x=-1/2
Here are the steps....
−7x+12+−2x=23+13x(−7x+−2x)+(12)=13x+23(Combine Like Terms)−9x+12=13x+23−9x+12=13x+23
−9x+12−13x=13x+23−13x−22x+12=23
−22x+12−12=23−12−22x=11
−22x−22‌=‌11−22‌x=‌−12
Hope this helps you!!

Answer:

The greatest depth of the Southern Ocean is 7.24 kilometers

Correct statement, question and data:

The table shows the greatest depths of four of the five oceans in the world. If the average greatest depth is 8.094 kilometers, what is the greatest depth of the Southern Ocean?

Please see the table attached.

Source:

Question that can be found at mathpractice101

Step-by-step explanation:

Let's answer the question, this way:

Depth of the Southern Ocean = x

For solving x, we have:

(10.92 + 9.22 + 7.46 + 5.63 + x)/5 = 8.094

10.92 + 9.22 + 7.46 + 5.63 + x = 40.47 (Multiplying by 5 at both sides)

33.23 + x = 40.47

x = 40.47 - 33.23 (Subtracting 33.23 at both sides)

x = 7.24

The greatest depth of the Southern Ocean is 7.24 kilometers

Laura bernett is 5 ft-4 inches tall. she stands 12 feet from a streetlight and casts a 9-foot-long shadow. how tall is the stree

xxMikexx [17]

The ratio of the height (h) of the streetlight to its distance to the end of Laura's shadow is the same as the ratio of Laura's height to her distance from the end of her shadow.
.. h/(12+9) = 5'4"/9
.. h = (21/9)*5'4" = 12 4/9 feet
.. h = 12 ft 5 1/3 inches

The streetlight is 12 ft 5 1/3 inches tall.
