Answer:
y=43 (alternate angle)
in triangle ADC
97+y+x=180(,sum of interior angle of triangle is 180)
x=180-97-43
x=40
C < 5
there will be an open circle on 5....it is open because there is no equal sign in the problem.....the shading will be to the left....because less then is shaded to the left
y=2x so replacr the -y with -2x so 2x+6 is 8x. :)
Answer:
3710
Step-by-step explanation:
First of all, find the first number more than 100 that can divided by 9, and it's 108 (we'll call it as 'a') then, find the number less than 2000 that can divided by 9, it's 1.998 (we'll call it as 'Un')
Un = a + (n-1).b
1998 = 108 + (n-1).9
1998 = 108 + 9n -9
1899 = 9n
211 = n
and the total is
Sn = n/2 (a+un)
s211 = 211/2 (108+1998)
= 222.183
