12 divided by 0.2 without a calculator is 60.
Answer:
x=-1, y=3
Step-by-step explanation:
3x+2y=3
3x-2y=-9
since we have -2y and 2y we can just add the equations
6x=-6
x+0y=-1
x=-1
to solve x using elimination multiply the top equation by -1
-3x-2y= -3
3x-2y=-9
and add
0x-4y=-12
-4y=-12
y=3
and substitute x and y to double; check
3(-1)+2(3)=3
-3+6=3
3=3
checks out so these are correct
Answer:
The time at which the car arrives at its destination is 0625 hours or 6: 25 am or 25 minutes past 6.
Step-by-step explanation:
Departure time = 0540 Hours means 5: 40 am or 40 minutes past 5 in the morning.
Now add 45 mins
Hours : Minutes
5: 40
<u> + 45</u>
<u> 5 : 85</u>
<u />
But 1 hour contains 60 minutes so 85 - 60 gives 25 minutes . those 60 minutes = 1 hour are carried over the hours and added .
Hours : Minutes
1
5: 40
<u> + 45</u>
<u> 6 : 25</u>
The time at which the car arrives at its destination is 0625 hours or 6: 25 am or 25 minutes past 6 in the morning.
Hi there
annual premium
7,000÷10years=700 per year
quarterly premium
Quarterly means 4 times a year so
7,000÷(4×10)=175 per quarter
difference between them
700−175=525
Good luck!
