Answer:
I think the answer is C. 7
Step-by-step explanation:
Since the angle is a right angle you first subtract 55 from 90.You are left with 35.
Secondly we have to divide 35 by 5 to find x.
Therefore 35÷5= 7.
I hope this helps you in any way.

Answer: x=45
Step-by-step explanation:
2x+6=96
2x=90
x=45
The smallest number of students in the class is the smallest number that is divisible by 2, 3, and 4. You need the least common multiple of 2, 3, and 4.
This is like finding the least common denominator.
Find the prime factors of the three numbers:
2 = 2
3 = 3
4 = 2^2
To find the LCM you need common factors, and not common factors with the larger exponent.
Now single factor is common to all numbers.
There is 2 and 2^2, so use 2^2 since it has the larger exponent.
There is also a 3, so use the 3.
LCM = 2^2 * 3 = 4 * 3 = 12
Mr. Carson's class may have 12 students. 12 is the smallest number of students it can have.
