Answer: 72
Plan A = 30 +0.15x
Plan B = 16 +0.20x
30+0.15x = 16+0.20x
subtract 16 from each side
14 +0.15x = 0.20x
subtract 0.15x from each side
14=0.05x
x = 14/0.05 = 280 minutes
280*0.15 = 42 +30 = $72
280 * 0.20 = 56 +16 = 72
280 minutes and cost $72 each

Answer:
270 cm^2
Step-by-step explanation:
area of atriangle =base*height/2
=30 cm * 18 cm/2
=540 cm^2/2
=270 cm^2
Simplify. Combine like terms
3 + x + 1 = 2
x + 4 = 2
Note the equal sign. What you do to one side, you do to the other. Isolate the x. Subtract 4 from both sides
x + 4 (-4) = 2 (-4)
x = 2 - 4
Simplify
x = -2
-2 is your answer for x
