How do you solve this whole thing please?

Answer:
Step-by-step explanation:
Let's look at the first two, and hopefully you'll be able to figure the rest out:
1. Answer below
[tex]d = rt[/tex]
The problem asks us to solve for [tex]r[/tex], so that means we need to get [tex]r[/tex] on one side of the equation by itself. To do so, we will need to divide both sides of the equation by [tex]t[/tex]:
[tex]\frac{d}{t} = \frac{rt}{t}[/tex]
[tex]\frac{d}{t} = r[/tex]
2. Answer below
[tex]B = T - Lc[/tex]
The problem asks us to solve for [tex]T[/tex], so that means we need to get [tex]T[/tex] on one side of the equation by itself. To do so, we will need to add [tex]Lc[/tex] to both sides of equation:
[tex]B + Lc = T - Lc + Lc[/tex]
[tex]B + Lc = T[/tex]
