Answer:
Hey there,
(It would be good to note that i just learned how to simplify/solve algebraic expretions)
P=21+2w
P/21=2w
then we flip it
2w=p/21 which could also be
w=2(p/21) i think

Basic Equality Properties
- Multiplication Property of Equality
- Division Property of Equality
- Addition Property of Equality
- Subtraction Property of Equality
Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify given.</em>
<em />
<u>Step 2: Solve for </u><u><em>k</em></u>
We can use equality properties to help us rewrite the equation to get <em>k</em> as our subject:
Let's first <em>square both sides</em>:
Next, <em>add p to both sides</em>:
Next, <em>divide 4t by both sides</em>:
We can rewrite the new equation by swapping sides to obtain our final expression:
∴ we have <em>changed</em> the subject of the formula.

Answer:
1.4 hours
Step-by-step explanation:
Runner A:
Speed = 8.1 mph
Time, = t
Runner B :
Speed = 6.3 mph
Time, = t
Distance apart = 20.16 miles
Distance = speed * time
Distance of Runner A + Distance of runner B = distance apart
8.1t + 6.3t = 20.16
14.4t = 20.16
t = 20.16 / 14.4
t = 1.4 hours
Number of hours, t = 1.4 hours
