175 students walk to school. 7+5=12 and 420 divided by 12 is 35. I checked how I did it was correct because of 5*35+7*35=420. Then I found the product of 5*35 which is 175.

June: 30-6=24
July: 31
August:31
September:30
October: 8
Total=24+31+31+30+8=124 days
Discount period:
The period of time between the date a bill of exchange is drawn and the date on which payment is due.
So discount period = 200-124=76 days
Let
A (-4,35)
B (-3,20)
C (-2,10)
D (-1,5)
E (0,8)
F (1,10)
G (2,15)
H (3,30)
I (4,48)
using a graph tool
case a) y=2.23x²+1.62x+5.26
see the attached figure N 1
case b) y=4.63x²+0.84x+4.14
see the attached figure N 2
case c) y=0.98x²+3.06x+6.02
see the attached figure N 3
case d) y=3.72x²+2.94x+3.21

therefore
the answer iscase a) y=2.23x²+1.62x+5.26
Angle A is 73 degrees.
This can be found by using the values for both angles and setting them equal to 180. Since they are alternating interior angles of intersections of parallel lines, they must equal 180.
6x - 35 + 3x + 53 = 180
9x + 18 = 180
9x = 162
x = 18
Since x = 18 we can place that into the equation for angle A in order to find it's value alone.
6x - 35
6(18) - 35
108 - 35
73
