Answer:
AC = 23 so it be D
Step-by-step explanation:
plug AC = DF ---> 21x-19 = 3x+17
sub. 3x by both sides --> 18x-19 = 17
add 19 to both sides --> 18x = 36
divide both sides by 18, x = 2
plug x back into 21x-19 to find AC
21(2) - 19
42 - 19 = 23
I = prt
420 = 7000 x .02 x t
420 = 140 x t
420/140 = 140 x t /140
t = 3 years
Answer:
what is it?
Step-by-step explanation:
oof- sorry I don't know the answer-
Answer:
243
Step-by-step explanation:
999-100= 899 integers
200s 400s 600s 800s excluded so 400 numbers excluded
899 - 400 = 499
20s 40s 60s 80s which are 40 integers x 4 = 160
499 - 160 = 339
2s 4s 6s 8s which are 4 integers x 6 x 4 ( 4 from each 100 ) = 96
339 - 96 = 243 integers
