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?
Answer:
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.

HELP what is -12=f-7
Answer:
F = -5
Step-by-step explanation:
-5 - 7 = -12
Think of it like this if you see a problem that goes like -4 - 3 then changed the minus symbol to a plus sign and change the 3 to a negative 3.
Answer:
f= -5
Step-by-step explanation:
-12=f-7 than u subtract the f to the other side giving you -f-12=-7 than you add the 12 to the -7 giving you 5 but than you have -f=5 and you need f to be bye it self and it's not bye it self because, it have the negative with it so you need to divide -1 into 5 giving you f= -5

Answer:
k = 9
Step-by-step explanation:
For this, we can factor the top expression to look like the bottom expression.
So, first we have to find the gcf of 18 and [tex]x^{2}[/tex] and add up to 11x.
18[tex]x^{2}[/tex] 11x
1 and 18 19 - No
2 and 9 11 - Yes
3 and 6 9 - No
So, the numbers are 2 and 9. The expression should now look like this:
[tex]x^{2}[/tex] + 2x + 9x + 18
Now, undistribute the terms.
x(x + 2) + 9(x + 2)
(x+2)(x+9)
This matches up with the bottom expression.
The value of k is 9.
The lines AB and CD are perpendicular to each other. If the slope of line AB is 2/3 then what is the slope of line CD
Answer:
-3/2
Step-by-step explanation:
you can find the perpendicular slope by putting the slope in 1/-m. M is the current slope you have or really you can flip it and change the signs so for example, 1/-(2/3) = -3/2
The slope of line CD is = -3/2
What are Perpendicular lines?A perpendicular is a straight line that makes an angle of 90° with another line.
Given that the lines AB and CD are perpendicular to each other, the slope of line AB is 2/3.
Slope of perpendicular lines are negative reciprocal of each other, so,
Hence, The slope of line CD is = -3/2

Of the 50 students in the cafeteria, 7 have red hair. Suppose there are 750 students in the school. Write a proportion that could be used to predict the number of students who have red hair. Use x to represent the number of students who have red hair.
Given:
Of the 50 students in the cafeteria, 7 have red hair.
Total number of students = 750
To find:
The proportion that could be used to predict the number of students who have red hair.
Solution:
Let x represent the number of students who have red hair.
The ratio of student having red hair to the total number of students are
[tex]Ratio_1=\dfrac{7}{50}[/tex]
[tex]Ratio_2=\dfrac{x}{750}[/tex]
The number of students having red hair is proportional to the total number of students. So, the above ratios are equal.
[tex]\dfrac{x}{750}=\dfrac{7}{50}[/tex]
Multiply both sides by 750.
[tex]\dfrac{x}{750}\times 750=\dfrac{7}{50}\times 750[/tex]
[tex]x=7\times 15[/tex]
[tex]x=105[/tex]
Therefore, the required equation is [tex]\dfrac{x}{750}=\dfrac{7}{50}[/tex] and the number of students who have red hair is 105.
