Express four times the sum of 
Take every word and translate into math.
Sum is addition.
Our sum is basically 
The we multiply 
Example Question #62 : How To Write Expressions And Equations
Express the difference between quotient of 
Take every word and translate into math.
Quotient indicates division. So we have 
Our expression so far is 
Then we have 
Then it asks for the difference of the two as our final anwer is 
Example Question #61 : How To Write Expressions And Equations
Express nine raised to the 
Take every word and translate into math.
Raised to a power deals with exponents.
So our answer is 
Example Question #64 : How To Write Expressions And Equations
Express three is greater than or equal to sum of 
Take every word and translate into math.
Greater than or equal to denotes 
Sum is addition.
Our sum is basically 
Our final answer is 
Example Question #65 : How To Write Expressions And Equations
Express fifteen less than 
Take every word and translate into math.
That something is 
Example Question #66 : How To Write Expressions And Equations
Express product of 
Take every word and translate into math. Product indicates multiplication.
So we multiply 
Is indicates equal something.
Difference is subtraction so we have 
Our final answer is 
Example Question #61 : How To Write Expressions And Equations
Translate the following sentence into an algebraic expression:
"The square root of the sum of 5 and twice an unknown number"
In order to translate the above sentence into an algebraic expression, let's consider each part of the sentence:
"The square root of the sum of 5 and twice an unknown number"
"The square root of..." means that we are going to take the square root, 
"The sum of 
"Twice an unknown number" means that we're going to multiply 
Putting all of the above together, we get 
Example Question #68 : How To Write Expressions And Equations
Translate the following sentence into an algebraic expression:
"Two-fifths times the reciprocal of an unknown number"
In order to translate the above sentence into an algebraic expression, let's consider each part of the sentence:
"Two-fifths times the reciprocal of an unknown number"
"Two-fifths times..." means that we're going to take the product of 
"The reciprocal of an unknown number..." means that we divide 
Putting all of the above together, we get 
Example Question #61 : How To Write Expressions And Equations
Translate the following sentence into an algebraic expression:
"Nine plus the quotient of an unknown number and six"
None of the above
In order to translate the above sentence into an algebraic expression, let's consider each part of the sentence:
"Nine plus the quotient of an unknown number and six"
"Nine plus..." means that we're going to take the sum of 
"The quotient of an unknown number and six" means the value we get when we divide an unknown number 
Putting all of the above together, we get 
Example Question #70 : How To Write Expressions And Equations
Translate the following sentence into an algebraic expression:
"The difference between 7 and the quotient of an unknown number and 3"
In order to translate the above sentence into an algebraic expression, let's consider each part of the sentence:
"The difference between 7 and the quotient of an unknown number and 3"
"The difference between 7 and..." means that we are subtracting the remainder of the expression from 7, or 
"The quotient of an unknown number and 3" means that we are dividing an unknown number - let's call it 
Putting all of the above together, we get
