Answer:
A
Explanation:
Let's say x represents adult tickets, and y represents child tickets.
We know that 2 adult tickets, x, and 2 child tickets, y, added together total $26. This can be written as:
2x+2y=26
We also know that 2 adult tickets, x, and 3 child tickets, y, added together total $31. This can be written as:
2x+3y=31
So, our system is:
2x+2y=26
2x+3y=31
Therefore, choice A is correct.

The Philadelphia convention was attended by all white men. Most delegates to the convention were young men aged between 20 and 30. Some re-owned political figures also attended the convention. The delegates who attended the convention were from mixed backgrounds.

1.) Without the atmosphere, average temperature on Earth would be freezing! Below zero to be exact!
2.) The atmosphere protects us and animals from dangerous radiation from the Sun. Ultraviolet radiation is basically invisible rays of energy created by the sun.
3.) Also, the atmosphere provides oxygen for humans and animals to breathe and C02 (Carbon dioxide) for plants.
4.) And lastly, the atmosphere protects us from objects coming towards the earth.
Hope this helps!
The appropriate answer is B. Chains of volcanoes along ocean coastlines. The theory of plate tectonics states that the earth's crust is divided into plates that float on the semi-molten mantle below. Plates can converge, diverge or slide past each other. Chains of volcanoes along coastlines are evidence of plates converging with one plate subducting beneath the other. The subducting plate will melt producing magma which is lighter than surrounding rock and so will force its way through cracks and fissures in the surface. Once magma reaches the earth's surface, volcanoes are formed.
