Yanira = Y
Tim = T
Hannah = H
-----------------
Therefore:
Y=T+3
Y=2H
T=H+2
---------------
Now, we know that:
Y=T+3
But we also know that:
T=H+2
Therefore:
Y=(H+2)+3
Y=H+5
-------------------
Now we can combine the equations:
Y=H+5
Y=2H
Therefore:
2H=H+5
2H-H=5
So, H=5.
---------------------
If H=5,
Y=2H=2*5=10
---------------------
If H=5,
T=H+2=5+2=7
-----------------------

Question:
Which expression is equivalent to the given expression using commutative property of addition? 2(x + b) + 3(xa).
Answer:
Option C:
3(xa) + 2(x + b)
Solution:
Given expression is 2(x + b) + 3(xa).
To find the equivalent expression using commutative property of addition.
Let us first define the commutative property of addition.
a + b = b + a
You can add in any order.
Now, write the given expression using commutative property.
2(x + b) + 3(xa) = 3(xa) + 2(x + b)
Option C is the correct answer.
Hence 3(xa) + 2(x + b) equivalent expression using commutative property of addition.
