Graph of y = tan x.
Answer:
4x-12=8x+12
-24=4x
-6=x
Step-by-step explanation:
put the variables to one side and numbers to the other side
then divide 4 from each side
now you have the answer
So he goes from side 2 to side 4 there is his cut have a nice day sir/maam
Answer:
33493.3
Step-by-step explanation:
Sphere
Solve for volume
V=4/3πr^3 4/3*3.14*20^3=33493.3
Let 
be the number of liters of the 10% solution she needs to use. She'd end up with a 6% solution with a volume of 
liters. The starting solution contains 0.04*9 = 0.36 liter of salt. Each liter of the 10% solution contributes 0.1 liter of salt, so that
Solve for :
so Mayra needs to add 4.5 liters of the 10% solution.
