Solve each equation for the given variable.?

Question

h = r/t (p - m) ---solve for r---

y = bt - c ---solve for b---

P - 2L + 2w ---solve for L---

g - 1.9 m/r2 (r2 as in r to the second power) ---solve for m---

Answer 1

h=r/t (p-m) assuming the (p-m) part is not in the denonminator,

then h/(p-m) = r/t dividing both sides by (p-m)
multiply both sides by t
then t*h/(p-m) =r where * is for multiplication

y=bt-c add c to both sides
then
y+c=bt divide both sides by t
then
(y+c)/t=b

P-2L +2w I am assuming this is geometric due
to the capitolizations and therefore
P-2L +2w =0
solving for L we add 2L to both sides
then
P +2w =2L
dividing both sides by 2
then
(P +2w)2 =L you can retype as P/2 +w =L

g-1.9 m/r2 I am assuming this is equal to zero also
g-1.9 m/r2=0
so subtracting g from both sides we get,
-1.9 m/r2 = -g
dividing both sides by -1.9 we get,
m/r2 = -g/-1.9 the negatives cancels out so,
m/r2 = g/1.9
multiply both sides by r2 to get
m= (g/1.9)*r2 where * is multiplication

Answer 2

1) h = r/t (p - m)

To get rid of the fraction, multiply both sides by t.

ht = r(p - m)

To isolate r, divide both sides by (p - m)

(ht)/(p - m) = r

2) y = bt - c

To solve for b, bring the -c over to the left hand side

y + c = bt

Now, divide both sides by t.

(y + c)/t = b

3) P = 2L + 2w

Subtract 2w both sides,

P - 2L = 2w

Divide both sides by 2

(P - 2L)/2 = w

4) g - 1.9 m/(r^2)

This has no equal sign. You can't solve for m.

Answer 3

Here are the first two. Are you sure there isn't an equal sign anywhere in the last two?

1) multiply both sides by t(p-m) and you get htp-htm = r

2) add c to both sides then divide by t and you get (y+c)/t = b

Answer 4

a million) h = r/t (p - m) To eliminate the fraction, multiply the two aspects through t. ht = r(p - m) To isolate r, divide the two aspects through (p - m) (ht)/(p - m) = r 2) y = bt - c to unravel for b, convey the -c over to the left hand edge y + c = bt Now, divide the two aspects through t. (y + c)/t = b 3) P = 2L + 2w Subtract 2w the two aspects, P - 2L = 2w Divide the two aspects through two (P - 2L)/2 = w 4) g - a million.9 m/(r^2) This has no equivalent sign. you could not resolve for m.

Answer 5

Multiply both sides by the bottom line so that:

r = h(t(p-m))
----------------------
y + c = bt

b = y + c/t
-----------------
P - 2w = 2L

L = P - 2w/2
----------------

g(r^2) = 1.9m

m = g(r^2)/1.9

Answer 7

r= ht(p -m)

b=(y + c) / t

L=(2w-p) / 2

m=(gr²) / 1.9
