Answer:
-70x + 21
Step-by-step explanation:
1-8 = -7.
-7(10x-3)
Distribute, you get -70x + 21.
If I’m correct then DE would be 15 and then AB would be 6.
Explanation: You would divide 24 by 8 and see by how much bigger triangle CDE is, and then for side DE you would multiply side BC by 3 and get 15, and then for side AB you would divide side DC by 3 and get 6! (I hope this helps)
Answer:
570 adults and 215 children
Step-by-step explanation:
did this assignment and got it right
5a + 2c = 3280 where a is adults and c is children
subtraction eliminates c, find a
3a + 0 = 1710
a = 1710/3
a = 570 adult and then you have to subtract 785-570= 215 children
