The answer is 7b+35 because the seven multiplies by the b and the 5 meaning that you multiple the number that’s on the outside with what’s on the inside and be b is a variable it cannot be multiplied so you combine 7 and b which gives you 7b and then you multiply 7 and 5 which gives you 35
The number of students that will need to buy the tickets is 419.
<h3>How many students will need to buy tickets?</h3>
The equation that can be formed from the information provided in the question is:
$20s < $1250 + $625 + $1470 + $12s
Where s represents the number of students
$20s < $3345 + $12s
$20 - $12s < $3345
$8s < $3345
s < $3345 / $8
s < 419

In order to form a triangle then the sum of its angles has to be equal to 180 degrees. In order to find out if it’s possible to form a triangle from a specific set of angles, then you have to add them up and see if they are equal to 180 degrees. If they are then it’s a triangle if they less than or greater than 180 then a triangle cannot he formed.

Answer:
Step-by-step explanation:
Denote this equivalence relation by 
(i.e, 
if and only if 
), is clear that 
is an equivalence relation since 
is. Now, by definition we have that ![[a]=\{b\sim a \mid f(a)=f(b) \}=f^{-1}(a)](https://tex.z-dn.net/?f=%5Ba%5D%3D%5C%7Bb%5Csim%20a%20%5Cmid%20f%28a%29%3Df%28b%29%20%5C%7D%3Df%5E%7B-1%7D%28a%29)
