Ok this inequality tells you the number of devices you can have before the new plan costs more than the old plan. The new plan expression is $4.50x + $94m = y ( total cost). The old plan is $175m = y (total cost). You can see m (number of months) in both equations, you don't need it this time since we're going to to compare both to one month. Since they're both equal to y you can make them equal to each other. $4.50x + $94 = $175. Now you want to figure when the new plan is less than the old plan you switch the equal sign for a less than sign. $4.50x + $94 < $175; this will help you find the inequality you want. From there just use algebraic steps to find that x has to less than 18 or
x < 18.
Answer:

AOB = 2 . x
2x = 60°
x = 30°
Answer:
x = 13/17
Step-by-step explanation:
27 = 34x + 1
34x = 27 - 1
34x = 26
x = 26/34
x = 13/17
I think the answer is 66. But I'm not sure just try and see...!
