Answer with Step-by-step explanation:
The Reflexive property states that for every real number x, x=x
Division property states that if a=b and we divide it by any non zero number c then also a/c=b/c
Multiplication property states that if a=b and we multiply it by any number c then also ac=bc
Addition property states that if a=b and we add it by any number c then also a+c=b+c
We are given that x= -6
Adding both sides by 6
⇒ x+6=0
Hence, it justifies the addition property.
Hence, correct option is:
D, Addition
Answer:
60m²
Step-by-step explanation:
24 = 2/5
12 = 1/5
12 × 5 = 60
60 = 5/5
It is 5:3 or 5/3
Divide it by 4
We apply our knowledge in variation.
The solution can be seen in the photo
b=9,a=12
I solved by substitution:
b = 3/4a ---> plug this into the other equation
a + b = 21 is now a + 3/4a = 21
Reduce: 7/4a = 21
a = 12
Now solve for b:
b=3/4a is now b=3/4(12)
b=9
-8(3x-2y)
Factor out each number because 8 times 3 equals 24
And -2 times -8 is 16
