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!

x = 7
Step-by-step explanation:
Rearrange the equation to make x the subject.
Original:
7x + 3 = 52

7x = 52 -3
7x = 49
Divide both sides by 7
x = 49/7
x = 7

Delta equation is:

but we are interested in

because it determines the discriminant


which means that discriminant is positive :)
