Teacher will have 3 bottles of glue after he combines
<em><u>Solution:</u></em>
Given that,
The art teacher has 7 bottles of glue that are each 2/5 full
He combines them so he will have fewer bottles
<em><u>To find: bottles of glue does he have after he combines them</u></em>
From given,
Total bottles = 7
Each is 2/5 full
Therefore, multiply 7 with 2/5 to get total bottles of glues he will have after combining

Thus teacher will have 3 bottles of glue after he combines
Answer:
Shane started the problem correctly
Step-by-step explanation:
We are given problem (-5) - (-1 3/4).
Mariah started the problem as (-5) + 1 - 3/4
Shane started the problem as (-5) + 1 + 3/4
We need to find who started the problem correctly.
The problem should be started by converting the mixed fraction into improper fraction i,e

Now we will solve bracket by multiplying -1 with term inside the bracket i.e


Let's compare both the procedures now:
Mariah:



Therefore, Mariah did not start the problem correctly.
Shane:



Therefore, Shane started the problem correctly.
A statement also know as an axiom which is taken to be true without proof.
