Does anyone know how to do this ? !

Ah, all you have to do is combine 2/5m and 3/5m.

In this case:

=2/5m - 4/5 - 3/5m

=-1/5m - 4/5

=-m/5-4/5

Step-by-step explanation:

You are given:

Reorder using commutative property (putting like terms together):

Now we are going to bring down the -4/5 (there is nothing to do there).

(2/5)m and -(3/5)m have the same denominator all we have to do is figure out what is 2-3 which is -1

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.

answer: entity is prob the answer
