so i just started modeling and two step inequalities and my question is 62°f and it drops 2 degrees every hour .How many hours w as it before the temperature was below 40°
2 answers:
Answer:
11 hours
Equation:
62 - 2x = T
62 - 2(11) = 40
It was 11 hours because if the temperature drops 2 degrees after every hour, after 11 hours, the temperature would have dropped 22 degrees and 62 - 22 = 40.

Answer: 11
Step-by-step explanation: subtract 13 from 24 and then add the existing number on that I think
2(2p + m) = 3 - 5m
Distributive
4p + 2m = 3 - 5m
2m + 5m = 3 - 4p
7m = 3 - 4p
m = (3 - 4p)/ 7
Answer:
20.52

I used a calculator
Yes it is right (-10, 34) is a solution of y = 3x-4
Answer:
Step-by-step explanation:
1. Cos 52° = adj/hyp
Cos 52° = x/13
x = 13×cos 52°
x = 8.00
2. Sin70° = opp/hyp
Sin70° = 30/x
x sin70° = 30
x = 30/sin70°
x = 31.93
x ≈ 32
3. Tan∅ = opp/adj
Tan∅ = 45/51
Tan∅ = 0.8824
∅ = tan-¹(0.8824)
∅ = 41.42°
∅ ≈ 41°
