Alright, lets get started.
The question says there are 18 pair of eyes staring at the monkey.
Usually 1 pair of eyes are consideed for 1 person.
It means , 18 pairs of eyes means 18 animals.
Means 18 animals are staring at monkey when it grabs the apple from unicorn's mouth.
This 18 animals includes unicorn itself because when monkey was grabing the apple from unicon's mouth, unicorn must be looking at him.
So, number of animals present at that time in forest : 18 animals(including unicorn) + 1 monkey itself
Means total 19 animals
Hence the answer is, 19 animals are in the forest in this moment : Answer
Hope it will help :)
There are 11 animals in the forest
Further explanation
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
consisting of one phrase (monomial) to many phrases (polynomial)
• 2. variable
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
operations [tex]{\displaystyle \boxed{+},\boxed{-},\boxed{:},\boxed{x}}[/tex]
Words that can be used to express arithmetic operations are:
• 1. addition,
• plus
• more than
• sum
• and
• total
• greater than
• increased by
• 2. subtraction,
• minus
• difference
• take away
• subtract
• less than
• decreased by
• less
• 3. multiplication,
• multiply
• product
• double (multiply by 2)
• twice (multiply by 2)
• triple (multiply by 3)
• quadruple (multiply by 4)
• times
• 4. division.
• quotient
• divided by
• ratio
• share
• into
• over
Sparkles the unicorn is in the forest,this counts for 1 animal
The monkey grabs the apple, this counts for 1 animal
There are 18 pairs of eyes staring at the monkey, it means there are :
18 : 2 = 9 animals
Arithmetic operations are :
Total animals = x = The unicorn + The monkey + 9 animals(18 pairs of eyes)
[tex]\displaystyle x=1+1+9[/tex]
