X = 3
AC = 8
explanation:
to find the value of x:
set AB + BC = AC
2x + x - 1 = 5x - 7
x = 3
to find the value of AC:
plug in x (3) into the AC expression
5(3) - 7 = ?
AC = 8

Answer:
Explanation:Egypt, country located in the northeastern corner of Africa. Egypt’s heartland, the Nile River valley and delta, was the home of one of the principal civilizations of the ancient Middle East and, like Mesopotamia farther east, was the site of one of the world’s earliest urban and literate societies. Pharaonic Egypt thrived for some 3,000 years through a series of native dynasties that were interspersed with brief periods of foreign rule. After Alexander the Great conquered the region in 323 BCE, urban Egypt became an integral part of the Hellenistic world. Under the Greek Ptolemaic dynasty, an advanced literate society thrived in the city of Alexandria, but what is now Egypt was conquered by the Romans in 30 BCE. It remained part of the Roman Republic and Empire and then part of Rome’s successor state, the Byzantine Empire, until its conquest by Arab Muslim armies in 639–642 CE.
Answer:
The real observations are:
Moon rises in east, sets in west each day.
stars circle daily around north or south celestial pole
Positions of nearby stars shift slightly back and forth each year.
A distance galaxy rises in east, sets in west each day.
We sometimes see a crescent Jupiter.
Explanation:
Mercury it can seen from the Earth but no it phases.
Moon is seen in all parts of the Earth, the only difference is that in north pole the stars moves parallel to the horizon.
By the rotation of Earth the relative position of stars changes a little bit.
In the north pole a galaxy can be observed and in the south pole 2 galaxies.
Jupiter is one of the planets that can be seen from Earth in some seasons and it changes the position due to the rotation of planets around the sun.
A planet beyond Saturn is not possible to be observed from Earth just with the naked eye.
