Answer:
P1 = P2 - ma*t
Step-by-step explanation:
ma= P2-P1/t
we multiply by t both sides of the equation
ma*t = (P2 - P1)*t/t
ma*t = P2 - P1
we sum by P1 both sides of the equation:
P1 +ma*t = P2 - P1 +P1
We ave:
P1 + ma*t = P2
we subtract by ma*t both sides of the equation:
P1 + ma*t -ma*t = P2 - ma*t
finally we have:
P1 = P2 - ma*t
Answer:
im not really smart lol
Step-by-step explanation:
<span>seventy two hundredths</span> = 0.72.
Decrease = Subtraction.
Two Tenths = 0.2
So:
0.72 - 0.2
0.72 - 0.2 = 0.52
So, This Expression Is Equal To 0.52
7 squared equals 7 times 7
