Most students in the seventh grade have a difficult time when it comes to algebra, and this is mostly because they do not have after class practices on what they learn daily. Are you looking for some questions to refresh your mind on what you covered this past week? Why don’t you take the one below and get to do just that?

Questions and Answers
• 1.

### Name the property that is illustrated.3 * (4 * x) = (3 * 4 ) * x

• A.

Communative property of multipilcation

• B.

Associative property of multipilcation

• C.

Distributive property of multiplication

• D.

Identity property of multiplication

Correct Answer
B. Associative property of multipilcation
Explanation
The given equation shows that the multiplication operation can be rearranged without changing the result. This property is known as the associative property of multiplication.

### Name the property that is illustrated .y+16=16+y

• A.

Associative property of addition

• B.

Identity property of addition

• C.

Distributive property of addition

• D.

Communative property of addition

Correct Answer
D. Communative property of addition
Explanation
The given equation, y + 16 = 16 + y, demonstrates the commutative property of addition. This property states that the order of adding two numbers does not affect the result. In this case, swapping the positions of y and 16 does not change the sum, indicating the commutative property.

### Simplify the expression.17+19+3=

• A.

41

• B.

36

• C.

39

• D.

51

Correct Answer
C. 39
Explanation
To simplify the expression 17 + 19 + 3, we add the numbers together. 17 + 19 equals 36, and then adding 3 to 36 equals 39. Therefore, the correct answer is 39.

Rate this question:

• 4.

### Name the property .4x=x*4

• A.

Identity property of multiplication

• B.

Communative property of multipilcation

• C.

Distributive property of multiplication

• D.

Associative property of multipilcation

Correct Answer
B. Communative property of multipilcation
Explanation
The given equation, .4x = x*4, demonstrates the commutative property of multiplication. This property states that the order of the numbers being multiplied does not affect the result. In this case, the equation shows that multiplying .4 by x is equivalent to multiplying x by 4, which confirms the commutative property.

• 5.

### Write the prouduct using the the distrubutive property.7(19)

• A.

63

• B.

487

• C.

25

• D.

133

Correct Answer
D. 133
Explanation
The correct answer is 133 because when we apply the distributive property, we multiply the number outside the parentheses (7) by each term inside the parentheses (19). This gives us 7 times 19, which equals 133.

• 6.

### Write the ratio in the simpilest form.6 lemons to 15 limes

• A.

3/2

• B.

6/15

• C.

2/5

• D.

6/9

Correct Answer
C. 2/5
Explanation
The ratio of 6 lemons to 15 limes can be simplified to 2/5 by dividing both numbers by their greatest common divisor, which is 3 in this case. This simplification gives us the simplest form of the ratio.

Rate this question:

• 7.

### Write the ratio in the simpilest form.50 pens to 24 pencils

• A.

50/24

• B.

25/12

• C.

65/45

• D.

25/12

Correct Answer
B. 25/12
Explanation
The given question asks for the ratio of 50 pens to 24 pencils. To simplify this ratio, we can divide both numbers by their greatest common divisor, which is 2. After simplifying, we get the ratio of 25 pens to 12 pencils, which is equivalent to 25/12.

Rate this question:

• 8.

### What does an order pair tell?(2 , 6 )

Correct Answer
x-coordinate units right to left from 0 y- coordinate units up or down from 0
2 is x and 6 is y
Explanation
An ordered pair represents the coordinates of a point on a graph. In this case, the ordered pair (2, 6) tells us that the x-coordinate is 2, which means it is 2 units to the right of the origin (0). The y-coordinate is 6, indicating that it is 6 units up from the origin. Therefore, the ordered pair (2, 6) represents a point that is 2 units to the right and 6 units up from the origin.
