Answer:
x=7
Step-by-step explanation:
7 times 3 =21 and 21 times 1 =21 cross multiply or butterfly method
Answer:
Principal amount (P) = $10,000
Rate (R) = 1.5%
Time (T) = 4 years
Simple interest, I = P X R X T / 100
= 10000 X 1.5 X 4 /100
= 60000 / 100
= $600
Therefore, Balance = P + I
= 10000 + 600
= $10600
1. Subtract 4 from both sides
v - 4 = 2t
2. Divide both sides by 2
v - 4/2 = t
3. Switch sides
t = v - 4/2
8% less
100-8=92
P=present amount
F=future amount=f(t)
t=time in years
rate of decay is 8% or times 92%
![F=P(0.92)^t](https://tex.z-dn.net/?f=F%3DP%280.92%29%5Et)
is the equation or
![f(t)=P(0.92)^t](https://tex.z-dn.net/?f=f%28t%29%3DP%280.92%29%5Et)
is the equation or
Answer:
t=11
Step-by-step explanation:
31-20=11
so 11 miles left
