7-5x+1
Answer:
Addition and multiplication are both commutative. Subtraction, division, and composition of functions are not. For example, 5 + 6 = 6 + 5 but 5 – 6 ≠ 6 – 5. More: Commutativity isn't just a property of an operation alone.

far as Lia. Which equation can be used to
find m, the number of miles Lia walked?
Am= 4 x 20
B20 = 4 x m
C20 = m = 4
Dm = 20 + 4
Answer:
The relation for the distance cover by Tina and Lia is 20 = 4 × m
Option B
Step-by-step explanation
Given as :
The distance cover by Tina = = 20 miles
The distance cover by Lia = = m miles
According to question
Tina walked 4 times as far as Lia
So, The distance cover by Tina = 4 × The distance cover by Lia
Or, = 4 ×
I.e 20 miles = 4 × m miles
or. 20 = 4 × m
So, relation is 20 = 4 × m
Hence, The relation for the distance cover by Tina and Lia is 20 = 4 × m
I.e option B Answer
