<h3>Further explanation </h3>Algebraic expressions in mathematics are a combination of coefficients, numbers, variables, constants and arithmetic operations such as addition, subtraction, multiplication, and division.
The main composition of algebraic expressions are:
- 1. phrases
algebraic forms separated by arithmetic operations
consists of one phrase (monomial) to many phrases (polynomial)
- 2. variables
is a value that can be changed, can be in the form of letters, for example, x, y, a, b, etc.
- 3. constants
is a fixed value, can be a number
- 4. arithmetic operations ⇒ +, - , : , x
<em>If 100 coins have a total mass of 226.13g. What is the mass of a coin</em>
We can make this statement in the form of an algebraic equation :
100 coins=226.13 g
then the mass of a coin :
Answer: 19.71 feet
Explanation:
Given: Speed of Charlotte =58.6 mi/h
Since 1 hour = 3600 seconds
and 1 mile = 5280 feet
So, Speed of Charlotte = mi/ sec
She looks down at her phone and takes her eyes off the road for 4.36 s.
Since , Distance =
So, Distance =
Hence, Charlotte traveled 19.71 feet during this time.
