Illustrate commutative property of addition using the expression (3 + x) + y
Explanation
Review
Two basic properties of addition:
Commutative property – terms may be switched but it won’t affect its value.
Illustration:
apple + banana = banana + apple
A + B = B + A
Associative property – Changing terms in a grouping is a change in association.
Illustration:
(Lyca + John) + Trish = (Lyca + Trish) + John
(L + J) + T = (L + T) + JRate this question:

On a scale was an apple. Two apples were added per hour. As a result, The weight increased. What model of addition is being illustrated above?
- A.
Commutative model of addition
- B.
Slide Model
- C.
Two dimensional Slide model
- D.
Putting together model
Correct Answer
D. Putting together modelExplanation
*Models of addition
Two models
Putting-together model – putting two or more things together is the same as adding.
Put 2 apples and 3 apples in one.
2 Apples + 3 Apples = 5 Apples
Slide-model- increase in distance or scale on a plane is also addition

The vertices of a triangle are A(1, 1), B(2, -1), and C(-1, 0). Moving all the points 3 units to the left and 1 units up. Locate the image of point B.
- A.
4th Quadrant
- B.
Y-axis
- C.
3rd Quadrant
- D.
X-axis
Correct Answer
D. X-axisExplanation
Moving all the points 3 units to the left and 1 unit up would result in the new coordinates for point B being (-1, 0). This means that the image of point B would be located on the X-axis.Rate this question:

Simplify the following expression. 3(x + 2) – 2(x - 3)
- A.
X-1
- B.
X +12
- C.
X
- D.
13x
Correct Answer
B. X +12Explanation
Steps:
Step 1: distribute to remove parenthesis
Step 2: switch all similar terms right next to each other.
Step 3: add similar terms.
Note: we can’t add 3x and 4. 3x has a variable while does not.
Tracing Misconception!
if you answered A:
you need to distribute 3 and -2 to all its corresponding terms inside each pair of parentheses "()"
if you answered c:
you probably forgot to include the sign of 2 in distributing.
if you answered d:
you probably added x + 12. Remember that they are dissimilar terms.

Given the figure above. Solve for x, if the to total area is 50 ft2.
- A.
1 ft
- B.
8 ft
- C.
7 ft
- D.
20 ft
Correct Answer
B. 8 ftExplanation
Use the formula: Area = Length x Width
Given:
Area = 50
Length = 5
Width = X + 2
injecting all values into the formula...
A = L * W
50 = 5 (X + 2)
then solve...
50 = 5x + 10
50 - 10 = 5x + 10 - 10
40 = 5x
40/5 = 5x/5

Solve! 2x = 3 x = ?
Correct Answer
1.5
3/2
one and a half
3 over 2Explanation
The equation 2x = 3 can be solved by dividing both sides of the equation by 2. This gives us x = 3/2, which is equivalent to 1.5. Therefore, the answer is 1.5.Rate this question:

Solve! x - 1 = 3 x = ?
Correct Answer
4Explanation
To solve the equation x - 1 = 3, we need to isolate the variable x. To do this, we can add 1 to both sides of the equation. This will cancel out the -1 on the left side, leaving us with x = 4. Therefore, the value of x is 4.Rate this question:

In the inequality 2x - 1 > 7, x can never be equal to 2!
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
In the given inequality 2x - 1 > 7, the goal is to solve for x. To isolate x, we first add 1 to both sides of the inequality, which gives 2x > 8. Then, we divide both sides by 2 to get x > 4. This means that x can take any value greater than 4. Since x cannot be equal to 2, the statement "x can never be equal to 2" is true.Rate this question:

Problem Solving The sum of a number and 7 is 33. What is the number?
- A.
40
- B.
26
- C.
25
- D.
27
Correct Answer
B. 26Explanation
To find the number, we can set up an equation based on the information given. Let's call the number "x". The sum of the number and 7 is equal to 33, so we can write the equation as x + 7 = 33. To solve for x, we can subtract 7 from both sides of the equation. This gives us x = 33 - 7, which simplifies to x = 26. Therefore, the number is 26.Rate this question:

Problem solving Jane paid P pesos, per day, for the replacement of the tiles in her bathroom. If labor cost was 250 pesos a day and each tile costs 15 pesos, how much will it cost her in a day T tiles are used?
- A.
P = 15T + 250
- B.
T = 15P+ 250
- C.
15T=250P
- D.
P =
Correct Answer
A. P = 15T + 250Explanation
Pattern
Y = ax + b
b = labor cost which is constant per day
a = number of tile which may change depending on how many are used...
Y is the P or the total cost per day..cause it depends on the number of tiles used in a day.
X is the T which independent variable...Rate this question:
