Solve x − 9/y= z for y.
1 answer:
Answer: (x-9)/2 = y
Basically, we ned to get y by itself. I started by multiplying both sides of the equation by y, which will cancel it out from the left side. That gives me x-9 = 2y.
Now, we're going to divide both sides by 2.
That gives me (x-9)/2 = y, which is your answer! I'll attach a photo of the work I did, I hope it makes sense! :)

Step-by-step explanation:
Akira receives the prize at the science fair for having the most informative project her trophy is in the shape of a square pyramid and is covered in shiny gold foil how much gold foil did it take to cover the trophy including the bottom
Total surface = surface area of the base square + area of 4 triangles
Calculate the surface area of the base square
surface area of the square = s^2
where s= side length
s=3 in
The surface area of the base =s^2
=3^2
= 9 square inches
The surface area of the side triangles
The area of the triangle = (1/2)* side length* slant height
Side length=3 in
Slant height=6 in
substituting the values,
The area of the triangle =1/2*3*6
= 18/2
= 9 square inches
There are 4 triangles
The area of 4 triangles = 4 x 9
= 36 square inches
Therefore,
Total surface = surface area of the base square + area of 4 triangles
= 9 + 36
= 45 square inches
