Someone help me with this

-7

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

3y+5=−16

Step 2: Subtract 5 from both sides.

3y+5−5=−16−5

3y=−21

Step 3: Divide both sides by 3.

3y

3

=

−21

3

y=−7

y= -7

Step-by-step explanation:

 5 + 3y = -16

-5             -5

Take away 5 from both sides and you get

3y = -21

so then you divide -21 by 3y and you get

-7

and there's ur answer :)  

y = -7

w = V / lh

Step-by-step explanation:

V = ℓwh

Where,

V=volume of a rectangular prism

l= length of the rectangular prism

w= width of the rectangular prism

h= height of the rectangular prism

Rearrange the quantities in this formula to give a new formula for the width of the rectangular prism.

V = ℓwh

It can be written as

V = l * w * h

w = V ÷ l * h

= V / lh

w = V / lh

Width of a triangular prism equals Volume of the rectangular prism divided by length of the rectangular prism times height
