Ok so
x - the smallest
The other 4 are : x+1, x+2, x+3, x+4
We know that sum is 120
So
x+x+1+x+2+x+3+x+4=120
Combine like terms
5x+10=120
Subtract 10 on both sides
5x=120-10
5x=110
Divide by 5 on both sides
X=22
The third number is x+2 = 22+2=24
Answer: The correct answer is C. 13/32
Step-by-step explanation: There are 32 students, and 11 + 8 = 19. SO in order to figure out how many students used blue, we need to subtract 19 from 32. that gives us 13. So:
13 out of 32 students, or
13/32
Answer: 
Step-by-step explanation:
Remembert that, by definition:
→ 
Then, you can rewrite
in exponential form:

Now you can solve for the variable "x":
Add 6 to both sides of the equation:


And finally you must divide both sides of the equation by 2, then:
