Remember that you can do anything to an equation as long as you do it to both sides
so
I=PRT
divide both sides by RT
=P
P=?
I=40
R=10%=0.1
T=5
plug it in
=P
=P
80=P
answer is B, $80
Answer:
D)
Step-by-step explanation:
One Half of a number +four =(is) three -(less) than quotien of five and a number :
1/2n+4=3−5/n Solve is :
X=-1 +- 3i
150 is smaller than 200 so 25 is smaller than 40, but 25, in perspective to the numbers, is much smaller than 40. Ana is faster.
Check:
Takashi: 200 divided by 400 equals 5 yd/sec
Ana: 150 divided by 25 equals 6 yd/sec
