Yes the answer would be B
Step-by-step explanation:
The problem bothers on fractions, here we are being presented with mixed fractions.
what we are going to do bascially is to subtract the sum of all the uloaded
peat moss in sites 1 and 2 to get from the peat moss to get the remaining for the third site
therefore

we then have to convert the mixed fraction to further simplify the problem we have

we then solve the fraction to the right of the negative symbol first

We can now convert to mixed fraction

For the third site the remainder is 5 12/25
The answer to this is D i did the math i am positive it is right
she should’ve written m-12 as m12
Multiply both sides of the second equation by 4. That will give you -4x in the second equation which when added to 4x of the first equation will eliminate x.
Second equation:
-x + 3y = 6
Multiply the second equation by 4 on both sides:
-4x + 12y = 26
