The three properties of algebra have been used below to find the number of students in the four sixth-Grade classes which is; 100 students
<h3>How to use properties of algebra?</h3>
There are 3 addition properties and they are associative property, identity property, and commutative property.
Commutative property is one that involves the aspect of just changing the order of the addends. Thus:
26 + 19 + 34 + 21 = 21 + 34 + 19 + 26 = 100 students
Identity Property is just adding a 0 to the number that doesn't change anything. Thus: 26 + 19 + 34 + 21 + 0 = 100 students
Associative property is one that involves just changing the grouping of the addends. Thus:
(26 + 19) + (34 + 21) = (26 + 21) + (19 + 34) = 100 students

If I’m correct, 3.25 would be the amount for each pound
This is a backup question it would be great to state what question 3 was please
Answer:
17
Step-by-step explanation:
Remark
In this formation, the chords cut each other so that
Equation
(3x - 1) * 3 = 12*(x -2) Remove the brackets.
Solution
9x - 3 = 12x - 24 Add 24 to both sides.
9x - 3 + 24 = 12x - 24 + 24 Combine
9x + 21 = 12x Subtract 9x from both sides
9x - 9x +21 = 12x - 9x
21 = 3x Divide by 3
21/2 = 3x/3
7 = x
Find QR
QR = 12 + x - 2
QR = 10 + 7
QR = 17
Answer:
line mo
Step-by-step explanation:
Because the triangle are congrument
RST and MNO are the triangle
RT is a line in the RST triqangle
it is equal to the MO line in MNO
