Let
x--------> the number of sessions
y-------> the total payment
we know that
without membership:
--------> equation 
with membership:
--------> equation 
using a graph tool------> resolve the system of equations
see the attached figure
the solution is the point 
that means
For 
the cost is
in both forms
so
to justify buying the membership

therefore
<u>the answer is</u>

Answer:
The triangles are similar by the AA similarity postulate
Step-by-step explanation:
The only thing we know is that the three angles are the same
70+30 +80 = 180 so the missing angle in each triangle is 80 in the first and 70 in the second
The triangles are similar by the AA similarity postulate
Andrew will run 32 miles.
Explanation:
If you divide the time Andrew ran by the miles he ran, you’ll get 7.5 minutes per mile. Then, if you divide 240 minutes by 7.5, you get 32 miles.
Answer:
a. 42 x 39 = 1638 ft²
b. small = 12(large)
small = 12(48)
= 576
576 - 48 = 528 more small posters
I remember that the square of 12 is 144.
Let's work up from there to the squares that 180 lies between.
Keep in mind that squares are when a number multiplies by itself.
For example;
10^2 means 10 • 10, which makes the product of 100.
12^2 = 144
13^2 = 169
14^2 = 196
Well, we have 169 and 196, which 180 lies between.
Your answers are:
13 and 14.
I hope this helps!
