Hey there! I'm happy to help! 
If Mary's friend at 3/4 of blackberries, we will simply multiply the total number of blackberries by 3/4 to find how many blackberries Mary ate. 
3/4×1 3/4= 1 5/16
Therefore, Mary's friend at 1 5/16 pounds of blackberries.
I hope that this helps! Have a wonderful day! 
 
        
             
        
        
        
Equation:
y + 2 = 1/3(x+1)
Assuming you are solving for Y:
y + 2 = 1/3(x) + 1/3(1)
(y + 2) - 2 = (1/3x + 1/3) - 2
y = 1/3x + 1/3 - 2
<u>y = 1/3x - 5/3</u>

Monomials are the expressions with one terms.
A.) 
Since, it has only one term. Therefore, it is a monomial.
B.) 
Since, it has two terms. Therefore, it is not a monomial.
C.) 
Since, it has only one term. Therefore, it is a monomial.
D.) 
Since, it has only one term. Therefore, it is a monomial.
E.) 
Since, it has only one term. Therefore, it is a monomial.
F.) 
Since, the variable is in the power. So it is not a monomial.
G.) 
Since, the power is not a integer. Therefore, it is not a monomial.
