Question

Easy algebra but i don't know how to do it lol

Answer 1

-5 +25-10m ≥ 60
20-10m ≥60
-10m ≥40
m ≤ -4 note flip equality sign because diving by a negative number

5 (4n+5)-4 ≤ 101
20n +25-4 ≤101
20 n +21 ≤ 101
20n ≤ 80
n ≤ 4

3(4-5p) -4 ≥ -67
12 -15p-4 ≥ -67
8 -15p ≥ -67
-15p ≥ -75
p ≤ 15 also flipped sign

-3(5m+2). &lt 54
-15m -6 &It 54
-15 m &Lt 60
m &lt -4

( I don’t know what sign &lt means I am assuming less than ? Just put the appropriate sign )

3x -4 (-5x+3) ≥ 57
3x +20x -12 ≥ 57
23x -12 ≥ 57
23x ≥ 69
x ≥ 3
