Primero se acomodan de menor a mayor y luego ubicaras el número que queda en medio
Your teacher is right. There is no reason to use algebra, which is misused in many problems as a shortcut, and slows the actual learning of math skills.
Here, the solution is as follows:
1. Find the volume of water in tank X.
2. Find the TOTAL base area of the three tanks, imagine that you have a larger tank with the same base area as the sum of the three.
3. Find the height of water in the new tank.
1. Find the volume of water in tank X.
Volume = 32*20*39.5=25280 cm^3
2. Find the TOTAL base area of the three tanks, imagine that you have a larger tank with the same base area as the sum of the three.
Total base area = 32*20 + 30*16 + 20*8 = 640+480+160 = 1280 cm^2
3. Find the height of water in the new tank
Height = Volume / base area
= 25280 / 1280
= 19.75 cm
The correct statements about the associative property to create equivalent expressions to a + b + (c + d) are as follows.
The associative property allows us to change the grouping of terms that are added together.
When changing the grouping, the order of the terms stays the same; only the parentheses change position.
The expression a + (b + c) + d is an equivalent expression.
The expression (a+ b) + c + d is an equivalent expression.
Given
Use the associative property to create equivalent expressions to a + b + (c + d).
<h3>Associative property;</h3>
Associative property explains that the addition and multiplication of numbers are possible regardless of how they are grouped.
The correct statements about the associative property to create equivalent expressions to a + b + (c + d) are as follows.
- The associative property allows us to change the grouping of terms that are added together.
- When changing the grouping, the order of the terms stays the same; only the parentheses change position.
- The expression a + (b + c) + d is an equivalent expression.
- The expression (a+ b) + c + d is an equivalent expression.

Answer:
3/6=1/2
Step-by-step explanation:
Answer:
<h2>4,8 and 16</h2>
Let the three numbers be a,ar, ar^2 ,
where r is the common ratio.
⇒a+ar+ar^2 =28 and a^3 r^3 =512
⇒ar=8⇒a+ar^2 =20
⇒8r^2 −20r+8=0
⇒r=2,r= 1/2
If r=2,a=4
Therefore, the three numbers are 4,8,16.
