Answer:

Step-by-step explanation:

rewrite each equation

1) 2x+12y=68

2)8x-12y=-28

because the y values are the same number but opposite signs they will cancel out nicely.

10x=40

x=4

now lets plug x into any of the equations.

2(4)+12y=68

12y=60

y=5

(4,5)

cirrus clouds form at a height of more than 6000 meters above the earth. write an inequality that represents h, the height, in m

Alecsey [184]

Cirrus clouds form at a height of more than 6000 meters above the earth. This means the inequality should represent the height more than 6000. The correct inequality for this case will be:

$h\ \textgreater \ 6000$

This inequality shows that h which is height where Cirrus clouds are formed is greater than 6000m.
