Answer: y = 0
Step-by-step explanation:
The choice shows 19 + 32 + 11 rewritten correctly using the commutative property and then simplified correctly is option B; 19+11+32= 30+32 = 62.
<h3>What is the commutative property of addition?</h3>
The commutative property of addition says that it doesn't matter how we add two numbers, the result of the addition would be same.
For two numbers x and y, we have:
x + y = y + x
WE have given
19 + 32 + 11
The sum would be 62.
We know that by commutative property of addition,
For two numbers x and y,
x + y = y + x
Thus, if we take 3 numbers as a,b and c, then:
c + a + b = c + b + a
Similarly,
19 + 32 + 11 = 19+11+32
= 30+32
= 62
Therefore, the option B is the correct answer.

Answer: Justin: 21 dollars, Raina: 16 dollars, Cho: 42 dollars.
Step-by-step explanation:
Let's say that Justin has x dollars.
Since Raina has 5 dollars less than Justin, Raina has (x - 5) dollars.
Since Cho has 2 times of what Justin has, Cho has 2x dollars.
In total, they have 79 dollars. So by adding up our quantities, they will equal 79 dollars.
x + (x - 5) + 2x = 79
So: 4x - 5 = 79
So 4x = 84
So x = 21
Therefore Justin has 21 dollars
Since Raina has 5 dollars less than Justin, Raina has 16 dollars
Since Cho has 2 times of Justin, Cho has 42 dollars
The answer would be -4 3/20. If you divide 83 by 20 you will get 4 R3 resulting in the mixed number -4 3/20
Answer:
2, 4, and 6
Step-by-step explanation:
Supplementary angles are angles that add to 180°.
We can see that the angles that make a straight line/straight angle with ∠7 are supplementary to it, because a straight line is 180°.
Those numbers would be be 2, which equals to 4, which equals to 6 and also 8, but that number isn't one of the answers
2,4, and 6
