I know thats the answer but I have no idea how you solve to get it. Im looking for help too.
Answer:
x=2
y=1
Step-by-step explanation:
2x+y=5
3x+2y= 8
<=> 6x+3y=15
6x+4y=16
<=> -y=-1
2x+y=5
<=> y=1
2x+1=5
<=> y=1
2x=4
<=> y=1
x=2
Answer:
98
Step-by-step explanation:
for a 4 sided polygon you can only draw one diagonal from one vertex so it forms 2 triangles.
For 5 sides you get 3 triangles
For 6 sides - 4
For 7 sides - 5
For 8 sides - 6
Looks like we get 2 less triangles than the number of sides in the polygon
Answer for 100 sides is 98 triangles.
The question can be solved as follows:

Hence the value of the given expression in scientific notation is expressed as:
Answer: Your answer is 72
Step-by-step explanation:
You take 24 hours in a day then the 60 minutes per hour and multiply. 60 times 24. Then take that answer [1,440] and divide it into 103,680. 103,680 divided by 1,440. Your answer is 72.
