If Betsy has n quarters.  What expression could be used to find the total value of her coins in dollars?

• A.

25n

• B.

0.25 +n

• C.

25 + n

• D.

0.25n

D. 0.25n

Jed reads p pages each day in a 200 page book.  What expression could be used to find the number days it would take to read the book?

• A.

200/p

• B.

200p

• C.

200 + p

• D.

200 - p

A. 200/p
Explanation
To find the number of days it would take to read the book, we need to divide the total number of pages (200) by the number of pages Jed reads each day (p). Therefore, the expression that could be used is 200/p.

Which verbal expression does NOT represent   9 - x?

• A.

X less than nine

• B.

X decreased by nine

• C.

Subtract x from nine

• D.

The difference of nine and x

B. X decreased by nine
Explanation
"x decreased by nine" represents the expression x - 9, not 9 - x. In this expression, x is being decreased by nine, which means that nine is being subtracted from x. Therefore, the correct answer is "x decreased by nine" as it does not represent the expression 9 - x.

Rate this question:

• 4.

Write "the product of 16 and n" as an algebraic expression.

16n
Explanation
The expression "16n" represents the product of 16 and n. This means that you would multiply 16 by the value of n to get the result.

Rate this question:

• 5.

Which of the following verbal expressions does NOT translate into  n + 3 ?

• A.

• B.

A number plus 3

• C.

A number decreased by 3

• D.

3 more than a number

C. A number decreased by 3
Explanation
The expression "a number decreased by 3" translates into n - 3, not n + 3.

Rate this question:

• 6.

Which of the following equations could be used to find the area of a rectangle with side lengths of 5cm and 7cm?

• A.

A = 5 + 5 + 7 + 7

• B.

A = 1/2 ( 5 )( 7 )

• C.

A = 5 + 7

• D.

A = (5)(7)

D. A = (5)(7)
Explanation
The equation A = (5)(7) can be used to find the area of a rectangle with side lengths of 5cm and 7cm. This is because the formula for the area of a rectangle is length multiplied by width, and in this case, the length is 5cm and the width is 7cm. Therefore, multiplying 5 by 7 gives us the area of the rectangle.

Rate this question:

• 7.

Which phrase represents the expression 7x + 2 ?

• A.

Seven times two plus a number

• B.

Two times a number plus seven

• C.

Two less than a number multiplied multiplied by seven

• D.

Two plus a number multiplied by seven

D. Two plus a number multiplied by seven
Explanation
The expression 7x + 2 represents "two plus a number multiplied by seven" because the variable x is being multiplied by seven and then two is added to the result.

Rate this question:

• 8.

Write an algebraic expression for  " 18 less than a number x "

x-18
x - 18
Explanation
The algebraic expression for "18 less than a number x" is x-18. This is because when we subtract 18 from x, we get the result of x being decreased by 18. So, x-18 represents the number x with 18 subtracted from it.

Rate this question:

• 9.

The state fair charges \$6 admission and \$2 for each ride.  Which expression could represent the total cost after admission is paid for one person and he/she rides "r" rides?

• A.

6 + 2r

• B.

2 + 6r

• C.

6 + 3r

A. 6 + 2r
Explanation
The given expression, 6 + 2r, represents the total cost after admission is paid for one person and he/she rides "r" rides. The expression starts with the initial admission cost of \$6 and then adds \$2 for each ride the person takes. This accurately reflects the scenario described in the question.

Rate this question:

• 10.

Which of the following equations represents the perimeter of a rectangle with sides L and W?

• A.

P = (L)(W)

• B.

P = L + W

• C.

P = 2L + 2W

• D.

P = (2L)(2W)

C. P = 2L + 2W
Explanation
The equation P = 2L + 2W represents the perimeter of a rectangle with sides L and W. This equation calculates the sum of the lengths of all four sides of the rectangle by adding twice the length (2L) and twice the width (2W).
