Step-by-step explanation:
Equation for Fast Internet is
45 + 50.45x
Equation for Quick Internet is
57.95x
To find when they cost the same , equate the 2 equations
45 + 50.45x = 57.95x ← required equation
Solve the equation by subtracting 50.45x from both sides
45 = 7.5x ( divide both sides by 7.5 )
6 = x
Both services would cost the same after 6 months

Answer:
original: 7.069
rounded: 7.1
Step-by-step explanation:
5x = 2 + 6y
Divide both sides by 5
x = 6/5y + 2/5
Input in the other equation.
2.4 = .3(6/5y + 2/5) + .4y
2.4 = .36y + .12 + .4y
2.4 = .76y + .12
Subtract .12 from both sides.
2.28 = .76y
Divide both sides by .76
3 = y
x = 6/5(3) + 2/5
x = 18/5 + 2/5
x = 20/5 = 4
(4, 3)
