Answer:
i think is angle 7 n angle 15
Step-by-step explanation:
I think it’s B if not srry
I believe it is the last one y>-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). < 54
-15m -6 &It 54
-15 m &Lt 60
m < -4
( I don’t know what sign < 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
