Which of the following best shows the associative property of addition?
a.4 + 5 = 9
b.(4 + 5) + 2 = 4 + (5 + 2)
c.4 + 5 + 2 = 2 + 5 + 4
Answer:
The answer is C: 4 + 5 + 2 = 2 + 5 + 4
Step-by-step explanation:
This is an example of the associative property of addition because the associative property of addition is described as any equation, that despite in what order your shift your equation to, the answer will stay the same. And as C shows, 4 + 5 + 2 will be rearranged to 2 + 5 + 4 and would still get the same answer, which would be 11.
The associative property of addition is represented by (4 + 5) + 2 = 4 + (5 + 2). The correct option is B.
What is associative property?
Rearranging the parenthesis in an expression will not change the outcome since some binary operations in mathematics have associative features.
The associative property is shown by the expression (4 + 5) + 2 = 4 + (5 + 2).
Solving the right-hand side:-
(4 + 5) + 2 = 9 + 2
(4 + 5) + 2 = 11
Solving the left-hand side:-
4 + (5 + 2) = 4 + 7
4 + (5 + 2) = 11
Therefore, the associative property of addition is represented by (4 + 5) + 2 = 4 + (5 + 2). The correct option is B.

A student writes an incorrect step while checking if the sum of the measures of the two remote interior angles of triangle ABC below is equal to the measure of the exterior angle.
In which step did the student first make a mistake and how can it be corrected?
Step 1; it should be m∠m + m∠n + m∠o = 180 degrees (sum of angles in a triangle)
Step 1; it should be m∠m + m∠n + m∠o = 90 degrees (adjacent angles)
Step 2; it should be m∠o + m∠p = 180 degrees (alternate exterior angles)
Step 2; m∠p − m∠o = 90 degrees (alternate interior angles)

Which equation has the correct sign on the product?
A. (-9)(-9) = -81
B. (-12)(4) = 48
C. (31)(-10) = -310
D. (26)(3) = -78
Answer:
C. (31)(-10) = -310
Step-by-step explanation:
A. (-9)(-9) = -81
negative times a negative is a positive incorrect sign
B. (-12)(4) = 48
negative times a positive is a negative incorrect sign
C. (31)(-10) = -310
positive times a negative is a negative correct sign
D. (26)(3) = -78
positive times a positive is a positive incorrect sign
Answer:
C. (31)(-10) = -310
Step-by-step explanation:
This equation has the correct sign, because multiplying a positive number and negative number gives you a negative number.
The other answer choices have the wrong signs.
Multiplying 2 negatives together gives a positive, so A is wrong.
Multiplying a negative by a positive gives a negative, so B is wrong as well.
D is wrong because multiplying 2 positive numbers gives a positive number.
So, C is correct.
