Answer:
60 hot dogs and 180 soda
Step-by-step explanation:
Soda was sold 3 times the number of hot dogs, and there were 240 in total.
So the equation would be:
3x + x = 240
3x being the number of soda and x being the number of hot dogs which like i sad earlier adds up to 240.
3x + x = 240
4x = 240
x= 60
60 being the amount of hot dogs and 3 time of soda would be 180 and adding them both up would be 240
Answer:
Step-by-step explanation:
We know the property of derivative: 
Given function : 
Differentiate both sides with respect to x , we get

[By Chain rule]

[Since
, where a is scalar and
]

Hence, the derivative of the given function is
.
