Answer:
3 kg
Step-by-step explanation:
Inverse relation:
y = k/x
In this case, the acceleration is inversely proportional to the mass, so using a for acceleration and m for mass, we have:
a = k/m
We need to find the value of k.
We use the given information to find k.
a = 9 m/s^2 when m = 5 kg
a = k/m
9 = k/5
k = 9 * 5 = 45
Now we can complete our equation:
a = 45/m
For a = 15 m/s^2, m = ?
15 = 45/m
15m = 45
m = 45/15
m = 3
Answer: 3 kg
Answer:
what grade level?
Step-by-step explanation:
Hi!




Explanation: <u><em>First you had to add by 3 from both sides. It gave us -3a=3p+1. Then divide into -3 from both sides. It gave us -3a/-3=3p+1/-3, or a=-p+-1/3 is the right answer. Hope this helps! And thank you for posting your question at here on Brainly. And have a great day. -Charlie</em></u>
Answer:
7-5n
Step-by-step explanation:
first you multiply both sides and get the equation 2n+2-7n+7 then you rearange the numbers to 2n-7n +2+7 and get -5n+7. you can change that to 7-5n.
One is that they are all <em>real numbers</em>, or <em>rational numbers</em>.
