Im thinking 9. If i did the math correctly. You should try 9
0.14x + 25 = 0.19x
25 = 0.05x
x = 500
the costs of the two plans will be equal after 500 minutes
Answer:
Your first step should be to separate the x's and the numbers.
This is how I would do it:
-3x+2-5x-7=4x+2
-3x-5x-4x=2-2+7
-12x=7
x=-7/12
9(2x4y2)3(3x5y3)4
=72x12y681x20y12
=7281x8y6
=89x8y6
Well u can't get division but division is the opposite of multiplication so if it was 12 divided by 2 it would be 6 because 6 times 2 is 12
