Hey, Please help!!

Mazyrski [523]

Step-by-step explanation:

1. d = rt

Divide t from both sides.

$\frac{d}{t} = r$

2. PV = nRT

Divide P from both sides.

$V = \frac{nRT}{P}$

3. $\frac{x}{2} -g=a\\$

Add g to both sides.

$\frac{x}{2}$ = g + a

Now multiply by 2 on both sides.

x = 2(g + a)

(or, x = 2g + 2a)

4. g $(h+\frac{3}{2} ) = 11$

Divide g from both sides.

$h + 1.5 = \frac{11}{g}$

Now subtract 1.5 from both sides.

h = $\frac{11}{g} -1.5$

5. $a(n-2)+5=bn\\$

n = $\frac{2a-5}{a - b}$
