Answer:
400
Step-by-step explanation:
8 x 50 = 400
400 files
If each folder has 50 files, you would multiply the number of folders by the number of files. So it would be 50 x 8 which equals 400 files.
true for all x
3x - 4 ≤ 2
Add 4 to each side
3x - 4+4 ≤ 2+4
3x<6
Divide by 3
3x/3 <6/3
x<2
or
2x + 11 ≥ -1
Subtract 11 from each side
2x + 11-11 ≥ -1-11
2x≥ -12
Divide by 2
2x/2 ≥ -12/2
x ≥ -6
x<2 or x ≥ -6
= 7
3(x−4)+9=18
3 − 1 2 + 9 = 1 8
3 − 3 = 1 8
3 = 1 8+3
3 = 21
x= 21/3
x=7
