Mathematics
1 answer:
marysya [2.9K]3 years ago
5 0

Answer:

40

Step-by-step explanation:

if you used cross products you'd pair 8 with 100 and n with 20

That written out would be 8(100)=20n

8(100)=800

800=20n

Divide on both sides

800/20=40

20/20 (cancels out)

Therefore n=40

What are the two things that happen to water molecules when heat energy is added to air?
yuradex [85]

Answer:

When the heat is raised (for instance, as water is boiled), the higher kinetic energy of the water molecules causes the hydrogen bonds to break completely and allows water molecules to escape into the air as gas. We observe this gas as water vapor or steam.

Ryan earns $5 for each small dog he walks and $8 for each large dog he walks. Today he walked 9 dogs and made a total of $51. Ho
Shalnov [3]
Use a system of equations.

(x=# of small dogs, y=# of big dogs)

x+y=9 (times by -5) -5x-5y=-45
5x+8y=51

Then add the equations together and the x's cancel. 

3y=6
y=2

So he walked 2 big dogs and 7 little dogs.
