This year
2:7
18:?
well 2*9=18
so 7*9=63
18/63
(18+63=total 81 students)
Last year
1/8
multiply by 9
9/72
9 less students this year
Hello,
Answer A: no solution
line 1: (-6,3), (3,6)==>y-3=(x+6)*3/9==>x-3y=-15 (1)
line 2: (-3,1), (3,3)==>y-1=(x+3)2/6==> x-3y=-6 (2)
(1)-(2)==>0x=-9 ==> no solution
line 1 // line 2
Your answer simplified should be 1.6 or 1 3/5
=)
Answer:
2(9+2y)/15 Hope this helped!!
Step-by-step explanation:
You find the circumference and multiply it by the central angle. If the central angle is in degrees, you divide that by 360. If the central angle is in radians, you divide by 2pi.
