Define x:
----------------------------------------------
Let x be the number of students in the second class:
⇒second class = x
There are 3 more students in the first class than in the second class:
⇒first class = x + 3
There are 2 more students in the third class than in the second class:
⇒third class = x + 2
----------------------------------------------
Expression for each class:
----------------------------------------------
First class = x + 3
Second class = x
Third class = x + 2
----------------------------------------------
Expression for total number of students:
----------------------------------------------
Total = x + 3 + x + x + 2
Total = 3x + 5
----------------------------------------------
Find x:
----------------------------------------------
There are 80 students in total, so
3x + 5 = 80
3x = 75
x = 25
----------------------------------------------
Find the number of students in each class:
----------------------------------------------
First class = x + 3 = 25 + 3 = 28
Second class = x = 25
Third class = x + 2 = 25 + 2 = 27
--------------------------------------------------------------------------------------------
Answer: There are 25 students in the second class.

Answer: i think its $.13
Step-by-step explanation:
Y=-5x+b
using (5,22) y= -5x+22
using (-5,-29) y= -5x-29
If the annual rate in 10 years has the same quadralaterical value the answer would be 47.9 but we can make sure our answer is correct
what we know:
The cost changed in 10 years to 23.95
if the cost changed another 10 years it would be another 23.95, 23.95+23.95=47.9 Which is our answer pls mark brainliest
Answer: $87.50
Step-by-step explanation: Lets write an expression to represent this situation.
(8.50 x 6) + (7.30 x 5)
Next solve inside the parentheses first. 8.50 x 6 = 51 and 7.30 x 5 = 36.50
Now we add
51 + 36.50 = 87.50
So in total, Deshaun will earn $87.50
