The solution for 4x - 4 < 8 is x < 3
The solution for 9x + 5 > 23 is x > 2
The given inequality is:
4x - 4 < 8
Add 4 to both sides
4x - 4 + 4 < 8 + 4
4x < 12
Divide both sides by 4
The second inequality is:
9x + 5 > 23
Subtract 5 from both sides of the inequality
9x + 5 - 5 > 23 - 5
9x > 18
Divide both sides by 9
The solution for 4x - 4 < 8 is x < 3
The solution for 9x + 5 > 23 is x > 2

Answer:
250 students
Step-by-step explanation:
Another way of saying this is:
40% of all six-grade students are 100 of them.
So,
40% of total is equal to 100
We can translate this into an algebraic equation and solve for the total number of students.
Let total number of students be "t"
Also, note "of" means "multiplication" and "is" means "equal"
Lets translate word equation to algebraic:
"40% of total is equal to 100"
40% * t = 100
Converting percentage to decimal by dividing by 100, we have:
40% = 40/100 = 0.4
Now, we have:
0.4 * t = 100
We can now solve for t:
Hence,
the total number of students is 250
