Answer:

Step-by-step explanation:
The formula of a distance between two points:

We have two points (1, -5) and (-3, 6). substitute:

Answer:
he is correct he might have seen it's 3 times more than 18-29 which is 10% so he just multiplied 45 with 3
4x=20-8y
x=5-2y now use this value of x in the second equation...
3(5-2y)+6y=15
15-6y+6y=15
15=15 This is true for any y or x value.
So there are infinitely many solutions as the two equations describe the same line.
585 hotdogs in 45 minutes.
You can simply do 13 X 45
Because 13 is the amount of hotdogs a minute and 45 is the total time.
13 X 45 = 585
Hope this helped you
