Answer:
I think $10 is the answer
Answer:
x = 3
Step-by-step explanation:
49 - 19 = 30
-2x - 12x = 10x
30 / 10 = 3
72,429 rounded to the nearest ten-thousands is 70,000.
given h = 600 - 16t ( add 16t to both sides )
16t + h = 600 ( subtract h from both sides )
16t = 600 - h ( divide both sides by 16 )
t = 
when h = 400
t =
=
= 12.5 seconds
The answer is 10,5 i think
