Answer:
a) 
b) It takes 5.390 years to pay off the loan.
Step-by-step explanation:
(a) The differential equation for the variation in the amount of the loan M is

We can express this equation as:

(b) We can calculate this as M(t)=0

It takes 5.390 years to pay off the loan.
First you multiply 450 m ×300 m= 135,000 m
Then you convert to Kilometers 135,000 ÷1,000= 135 Kilometers
So the answer is 135 Kilometers
Answer:
114
Step-by-step explanation:
that's supplementary
-3/5x + 1/5 > 7/20
-3x + 1/5 > 7/20 join the denominators
-3x + 1 > 7/20 * 5 multiply both sides by 5
-3x + 1 > 35/20
-3x + 1 > 7/4
-3x > 7/4 - 1
-3x > 3/4
x < -3/4 ÷ 3
x < -1/4
hope that helps, God bless!
