The answer when evaluating 2[(9 + 3) ÷ 4]

What is 6 (explained: add 9 and 3, then divide by 4 then multiply by 2.

100
Given t = 2, the answer when evaluating: 5t + 2t
What is 14 ...the expression (5t + 2t) can actually be simplified to (7t) first and you would have still arrived at the correct answer.
100
The simplified form of the expression below: x + 2x + 3x
What is 6x
100
The variable expression represented by: "The sum of a number and nine"
What is n + 9...or 9 + n but we like to write expressions in ascending order with variable terms first followed by the constant.
100
The vocabulary word used to represent the 7 in the expression below: 5m + 7
What is the constant or constant term....the 'm' is the variable and the 5 is called the coefficient.
200

The answer when evaluating 6 + 32 ÷ 2^3

What is 10 (explained: First, you would need to do 2 to the 3rd power, then divide 32 by 8 and then add 6)

200
Given x = 5, the answer when evaluating: 13 + 2x
What is 23
200
The simplified form of the expression below: 4x + 5x + 7 + 9
What is 9x + 16
200
The variable expression represented by: "The difference of a number and 21"
What is n – 21
200

6x + 10 = 70 

What is X=10
300
The answer when evaluating 16 + (12 – 2 x 4)
What is 20
300
Given g = 7, h = 2 the answer when evaluating: 3g – 4h
What is 13
300
The simplified form of the expression: 4x + x + 5 + 2x
What is 7x + 5
300
The variable expression represented by: "The product of six and a number"
What is 6n
300

The simplified form of the expression: 2(5x + 6)

What is 10x + 12 (the distributive property, when we multiply everything outside the parenthesis by everything inside the parenthesis.)

400
The answer when evaluating 7 + 16 ÷ 8 x 2
What is 11
400
Given m = 4 and n = 2, the answer when evaluating: 10 + 6m ÷ n^3
What is 13
400

The simplified form of the expression: 2x + x + 5x + 3^2 + x

What is 9x + 9

400
The variable expression represented by: "one-third a number"
What is 1/3(n) ... the word "of" alone means multiplication and is used when dealing with fractions, decimals and percentages.
400
The simplified form of the expression: 4(2x + 1) + 2x
What is 10x + 4
500

The answer when evaluating 2 + 3[(5 + 1) ÷ 2]

What is 11 (explained: Solve 5 + 1 first, then divide it by 2. Next, distribute the 3, and then add 2. )

500
Given x = 2, y = 4 and z = 13 given the answer when evaluating: (3x)^2 + 2y^2 - 3z
What is 29
500

The simplified form of the expression below: 7 + 2^2 + x + 4^2 + x + 5x

What is 7x + 27

500
The variable expression represented by: " seven less than two times a number"
What is 2n – 7...whenever we see the word "than" we switch order.
500
The simplified form of the expression: 5(2x + 4) + 2(x + 1) + 4
What is 12x + 25
