24<0.05x
x>480
b. When the number of calls per month is greater than 480, then Plan 1 is more economical. Example: If the number of calls is greater than 480 say 500, then charges in plan 2 will be $39, but Plan 1 is more economical and charges will be $38.

Step-by-step explanation: It would be 15 in because 12+12 equals 24 and 50-24=30 and 30 divided by 2 equals 15 in.
Well for 3. you use the Pythagorean theorem to say that 28^2 - 18^2= x^2 so 21.4 and for 4. the Pythagorean theorem says a^2 + b^2 = c^2 with c being the hypotenuse of any right triangle so the sums of the two smaller squares make the sum of the larger square making the answer b
