Plz answer this math problems?

Question

name the axiom, theorem, or definition that justifies each lettered step... ex. A) something
9= -3/4y
-4/3(9) = -4/3(-3/4y) A)
-4/3(9) = [-4/3(-3/4)]y B)
-4/3(9) = (1)y C)
-4/3(9) =y D)
-12 = y

Answer 1

a)cross multiplication
b)re-arrange the brackets/formula
c)multiplying outside of the brackets
d) answer the remaining parts


happy to help =)

Answer 2

This simply uses the property of the equality. In particular, if

if a = b then ka = kb

I would also note the use of

1. The multpilicative inverse

a x k = 1 then k is the mutiplicative inverse. k=1/a with a<>0

2. The miltiplicative identity

a x k = 1 then k is the multiplicative identity. k=1

Hope this whay you are after. Onya....

Answer 3

A. multiplication property of equality
B. associative property of multiplication
C. inverse property of multiplication
D. identity property of multiplication
(The last step is most likely "substitution", though you don't have it labeled as a question.)

You will want to learn the properties. You'll certainly have a test over this soon.

Answer 4

a)cross multiplication
b)rearanging brakets/formula
c)multiplying outbrakets
d) answer

gimmie pooints 4 tht plse. Taxed my brain!!
