Answer:
x ∈ (-oo ; - 1) ∪ (+ 2 ; +oo)
Step-by-step explanation:

x ∈ (+ 2 ; +oo)

x ∈ (-oo ; - 1)
x ∈ (-oo ; - 1) ∪ (+ 2 ; +oo)
They are different because -7 is not equal to -17
1. 24/(63%-59%)= 24/4%= 6,so the phone drop one charge every 6 minutes of listening to top pop.
42/6=7(the percentage consumed in 42 minutes)
46%-7=39%(percentage of battery left)
2. 76%-16%=50%(percentage of battery consumed after watching 3 episodes of "the haunted cave")
80x100%=8.000%(maximum percentage of battery at which the phone can be charged 80 times)
8000%/50=160(episodes of "the haunted cave" the monkey can watch)
3.idk the answer, sorry
-7 + -3 = -10 So.... it can be any negative integers that would equal -10.
EX: -6 + -4 = -10 or -5 + -5 = -10
