(Btw that’s not 50 points, imma solve this for you because you’re desperate)
Using the Pythagorean theorem:
c^2 = a^2 + b^2
c^2 = 4^2 + 7^2
c^2 = 16 + 49
c^2 = 65
c = 8.1

t = 30a + 150 .
' t ' is the total cost of treatment.
' a ' is the number of appointments.
The $150 is paid only once.
I hope Pedro gets better fast. Poor little guy.

Oh, I see.
Now you're saying that she pays the $150 at every appointment.
So the equation is actually
<span>t = 180a</span>
First we have to make the fractions even so there denominator have to be equal. So 15 times 2 gets 30 and 6 times 5 gets 30 too. Ok now multiply the nominator by the corresponding number of 25/30 and 16/30. Subtract to get 9/30 now simplify to get 3/10.
<span>15 - 13(2x + 6) < 15 - 3(6x - 7)
15 - 26x - 78 < 15 - 18x + 21
-26x -63 < -18x + 36
-8x < 99
x > -99/8
or
x > - 12.375
