If the sum of difference of 13 and 4 divided 64 and 8 is subtracted from the result. Find that number. Mathematical equation plz
2 answers:
Step-by-step explanation:
Let x be the number subtracted from 13 such that the difference is 13-x
divide that resulting difference by 11, then it becomes (13 - x) / 11
Multiply the quotient by 8 then the expression becomes ((13-x)/11)^ * 8
the product comes to 8 then ((13-x)/ 11)^ * 8=8 solve the equation divide
both sides by 8, then (13 - x) / 11 = 1 cross multiply 13 - x = 11 add -13 to both sides - 13 + 13 - x = 11 - 13, - x = - 2 . x = 2 Therefore the number is 2

Answer:
Step-by-step explanation:
10a + 9b = 3c
Subtract 9b to isolate the variable a.
10a = 3c - 9b
Now we need a singular a, so divide equation by 10.
So that's how you do it.
Newton's Law of cooling is
where
T(t) = temperature of the body after t hours, 80 °F
= ambient temperature, 65 °F
= normal body temperature, assumed to be 98.6 °F
The elapsed time since death is obtained from
4.142 hours before 2 am is 9:52 pm (the previous day) approximately.
Answer: 9:52 pm the previous day.
