I need help with math hw. please!!!?

Question

OKAY, so im really bad at math and im starting to refresh on my math. please help?

Y/Z divided by Z/T = 1 SOLVE FOR Y?

E = MC2 C2 = ?

A = 1/2BH, H = ?

P= 21 + 2W, W =?

A = a+b+c /3, B = ?

=( please help my hw is due 2morrow and no one is around to teach me

Answer 1

1.  (y/z) / (z/t) = 1

Multiply both sides by z/t

y/z = z/t

Multiply both sides by z.

y = z²/t

2.  e = mc²

Divide both sides by m.

e/m = c²

3.  A = 1/2bh

Multiply both sides by 2.

2A = bh

Divide both sides by b.

2A/b = h

4.  P = 2L + 2W

Subtract 2L from both sides.

P - 2L = 2W

Divide both sides by 2.

(P-2L)/2 = W

5.  Should I assume that b and B are the same thing?  Usually b and B do not represent the same thing.

Also, is it A = a+b+c /3 ?

Or is it A = (a+b+c)/3 ?

Either way, I'll let you attempt this one.
