c. all three cultures had unique symbolism to represent their numbers.
d. there are two primary sources for ancient egyptian mathematics.
e. ancient chinese mathematicians did not attempt to solve systems of linear equations.

The following are the correct statements regarding mathematics in the Egyptian, Chinese, and Babylonian cultures:

Both Egyptian and Chinese number systems use base 10.

All three cultures had unique symbolism to represent their numbers . (Earlier symbols were used to depict things)

There are two primary sources for ancient Egyptian mathematics  

(The primary sources are the Rhind Papyrus and the Moscow Papyrus)

Step-by-step explanation:

The types of problems found on ancient papyri, books, and tablets focuses primarily on problems that relate to daily life. The solution methods for many ancient cultures are generally verbal, with mathematical statements written out in words. Why did most ancient cultures primarily write out their mathematical texts in words?

Most ancient societies had symbols to represent numbers, but they did not have symbols to represent operations or unknown quantities. Thus, the problems and solutions to the problems had to be written in word form.
