Answer: 160 miles.
Step-by-step explanation:
Equation = $142.40 = .24x + 104
Define Variable = x = number of miles driven
Solve Equation = Subtract 104 from each side:
38.40 = .24x
Divide both sides by .24:
160 = x
The van was driven 160 miles.

Hi my friend, how are you :)

Answer:
x = pi/2 + 2 pi n x = pi + 2 pi n where n is an integer
x = 5pi /3 + 2 pi n
Step-by-step explanation:
8 cos^2 x + 4 cos x-4 = 0
Divide by 4
2 cos^2 x + cos x-1 = 0
Let u = cos x
2 u^2 +u -1 =0
Factor
(2u -1) ( u+1) = 0
Using the zero product property
2u-1 =0 u+1 =0
u = 1/2 u = -1
Substitute cosx for u
cos x = 1/2 cos x = -1
Take the inverse cos on each side
cos ^-1(cos x) = cos ^-1(1/2) cos ^-1( cos x) =cos ^-1( -1)
x = pi/2 + 2 pi n x = pi + 2 pi n where n is an integer
x = 5pi /3 + 2 pi n
Answer:
6y^4+4x
Step-by-step explanation:
2x+x+x=4x
2y*3y*y*y=6y^4
Add these together, 4x+6y^4
arrange in standart form:
6y^4+4x
