History of mathematics
Several civilizations — in China, India, Egypt, Central America and Mesopotamia — contributed to mathematics as we know it today. The Sumerians were the first people to develop a counting system. Mathematicians developed arithmetic, which includes basic operations, multiplication, fractions and square roots. The Sumerians’ system passed through the Akkadian Empire to the Babylonians around 300 B.C. Six hundred years later, in America, the Mayans developed elaborate calendar systems and were skilled astronomers. About this time, the concept of zero was developed.

is BC a line segment, a ray, or a line
Answers
Answer:
Line Segment
Step-by-step explanation:
A line segment has dots on both ends of the line. A line has nothing at either end of it. A ray has an arrow at one end of the line. Line BC is a line segment.
Hope it helps!
Explanation:
This is because we have two fixed endpoints, B and C, where the line does not go on forever beyond those endpoints. This means BC is some fixed length. The terms "line segment" and "segment" are the same thing.
A ray on the other hand would have the line go on forever in one direction, while it only has one fixed endpoint. As the name suggests, think of the ray of sunlight as an example. So we can rule out "ray". We can also rule out "line" because it doesn't extend forever in both directions.

We replace every copy of x with 5. Then we apply the order of operations PEMDAS to simplify.
f(x) = -2x+1
f(5) = -2(5)+1 ..... x replaced with 5

A frame is 1 in wide and 4 in tall. If it is enlarged to a height of 20 in, then how wide will it be
Answers
A ratio shows us the number of times a number contains another number. The width of the frame after enlargement is 5 inches.
What is a Ratio?A ratio shows us the number of times a number contains another number.
Given that the frame is 1 inch wide and 4 inches tall. Now, if the frame is enlarged, then the ratio of the corresponding sides will be equal.
Further, given that height after enlargement is 20 inches. Therefore, if the ratio of the height of the before enlargement and after enlargement is taken, then it will be,
Ratio = After Enlargement/ Before Enlargement
Ratio = 20 inches / 4 inches
Ratio = 5
Now, if we use the ratio to find the width of the frame after enlargement, then the frame width will be,
Ratio = After Enlargement/ Before Enlargement
5 = Width after Enlargement/ Width before Enlargement
5 = Width after Enlargement/ 1 inche
Width after Enlargement = 5 inches
Hence, the width of the frame after enlargement is 5 inches.
