Step-by-step explanation:
The normal body temperature : to = 37° C
An inequality is:
| t - to | ≤ 3
| t - 37 | ≤ 3
t - 37 ≤ 3 AND ( - t - 37 ) ≤ 3
t ≤ 3 + 37 - t + 37 ≤ 3
t ≤ 40 - t ≤ 3 - 37
- t ≤ - 34 / * ( - 1 )
t ≥ 34
Answer t ∈ [ 34°C, 40° C ].

Step-by-step explanation:
Answer:
A 3
Step-by-step explanation:
Let n = the number
a number decreased by 12
n-12
This is equal to 3 times the opposite =
3 times the opposite
3*(-n)
-3n
Setting the two parts equal
n-12 = -3n
Subtract n from each side
n-n-12 = -3n-n
-12 = -4n
Divide by -4
-12/-4 = -4n/-4
3 =n
