Answer:
5x=55
Divide both sides by 5 to solve for x
5x/5=55/5
x=11
Answer:
3x36
Step-by-step explanation:
Because he is getting 36 3 times so 3x36
By a Fourth grader
This solution only needs proper understanding of the word problem and identification of variables.
Let x = number of hours rental of the canoe
It costs $5 per hour for a canoe. However, for every rental of one canoe, there is a deposit of $15 regardless.
The expression is then 5x + 15.
This expression will solve how much it costs in total to rent one canoe for x hours.
Answer:
the domain of the function = [0,12]
Step-by-step explanation:
Given that:
f(t) = 60 t - 5t²
at time t = 0
f(0) = 60 (0) - 5(0)²
f(0) = 0
the differential of f(t) is:
f(t)' = 60 - 10t
for the maximum height
f'(t) = 0
i,e
60 - 10t = 0
60 = 10t
t = 60/10
t = 6
Now, t = 6,
f(6) = 60(6) - 5(6)²
f(6) = 360 - 180
f(6) = 180
Hence, after 6 seconds, the stone is noticed to have raise to 180 m and 180 m drop after 6 seconds.
Hence, the domain of the function = [0,12]
