x − (−x) + y
x + x + y
= 2x + y.
Answer:D
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 8.5%/100 = 0.085 per year
putting time into years for simplicity
6 months ÷ 12 months/year = 0.5 years
then, solving our equation
I = 10000 × 0.085 × 0.5 = 425
I = $ 425.00
on a principal of $ 10,000.00
at a rate of 8.5% per year
for 0.5 years (6 months) is $ 425.00
Answer:
The train going 30 miles in 1/3 hour is going faster than the other train.
