Nitella [24]
Hey there, Elizabeth76265!

If the owner left only 3 cans of food for 5 days, that means that we have to divide those cans of food so we can just do simple math and divide 3 by 5
\frac{3}{5} and you get 0.6

So the cat must eat 0.6 of each can everyday.

Thank you for using Brainly.

Please use elimination<br> 3х - бу = 18<br> 2x + 2y = 6
Molodets [167]

Answer:

x = 4

Step-by-step explanation:

3x - 6y = 18

2x + 2y = 6 -> 3(2x + 2y = 6)

3x - 6y = 18 -> Cross out - 6y

6x + 6y = 18 -> Cross out + 6y

9x = 36 -> Divide 9 on both sides.

X = 4

If £100 feeds 80 children for 5 days, what is the cost to feed 1 child for 1 day.
timurjin [86]
So basically you want to find the cost per day. So you have 5 days, so divide £100 by 5.

You get £20 per day

Now, the cost per child. We have 80 children so it would be £20/80 children per day.

Our answer is £0.25 per child per day.
