4y = 8.4 what is the value of y?
also pls include an explanation for this along with a check ( a sentence to check the answer ) and property ( commutative, associative, distributive, or identity ) ;-; ill give 5 stars and a thanks

2.1

Step-by-step explanation:

You divide 8.4 by 4 hope this helps

Work Shown:

4y = 8.4

4y/4 = 8.4/4   divide both sides by 4; division property of equality

y = 2.1

Check:

4y = 8.4

4*2.1 = 8.4 replace y with 2.1

8.4 = 8.4

We end up with a true equation, as we get the same number on both sides, so we've confirmed the answer.

  21.3

step-by-step explanation:

multiplying the given equation by c/sin(25°), we get

  c = 9/sin(25°) ≈ 21.2958 ≈ 21.3

we assume "c" is the length of ab, the side opposite angle c in triangle abc.

it’s supposed to be -4+45=41
