Answer:
3
Step-by-step explanation:
Let x represent the number. The problem statement tells you ...
2/3(3x +6) = 10
2x +4 = 10 . . . . . . use the distributive property
x +2 = 5 . . . . . . . . divide by 2
x = 3 . . . . . . . . . . .subtract 3
The number is 3.

<em>Comment on the solution</em>
The above shows an "alternative" solution method. The more usual way this might be done is ...
2(3x +6) = 30 . . . . . multiply by 3 to clear fractions
6x +12 = 30 . . . . . . . eliminate parentheses
6x = 18 . . . . . . . . . . . subtract 12
x = 3 . . . . . . . . . . . . divide by 6
Answer:
That doesn't make sense, it's wrong. t=60 because 45+15=60
Step-by-step explanation:
Answer: The derivative of the function
is
.
Step-by-step explanation:
We know that the derivative of
with respect to x is given by :
(1)
The given function is 
Differential both sides with respect to x , we get

( Using (1))
Therefore , the derivative of the function
is
.
