Answer: 47°C
Step-by-step explanation:
Since we are given the velocity, all we have to do is plug in 358 for v and solve for t.
[divide both sides by 20]
[square both sides to cancel out square root]
[subtract both sides by 273]
Now that we know the temperature is 47.41°C, we know our answer choice is D.
9y = 6x + 54
divide through by 9:-
y = 6/9y + 54/9
y = 2/3 x + 6 <---- answer
