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

Answer:
m=81
Step-by-step explanation:
14 x 1.5 = 21
54 x 1.5 = 81
Answer:
1518
Step-by-step explanation:
In order to draw x ≤ -10 on a number line, first draw a closed dot at -10. This is because we have a ≤ and not a <. If we had a <, it would be an open dot.
Next, since we want x to be smaller, draw an arrow pointing towards all numbers that are smaller. This arrow would point to the left.
