You have five and a half sticks of butter you need me back to the you can bake it takes 3/4 of a stick to make a batch how many batches can you bake

You can make 7 batches.

Step-by-step explanation:

Five and a half sticks of butter is equivalent to 22/4. 22 divided by 3 is 7 and 1/3, but 1/3 is not a full batch. Therefore you can make 7 batches.

Hey there!

So, first, you need to rearrange the second equation so y is in front.

x+y=10

Subtract x.

y=10-x

Plug that in for y.

2x+3(10-x)=45

2x+30-3x= 45

Subtract 30 on both sides.

-x= 15

Divide by -1 on both sides.

x=-15.

I hope this helps!
