Answer:
y = 7
Step-by-step explanation:
Equate the equation to equal 0.
8(y-7) = 0
Open up the bracket:
8y - 56 = 0
Add 56 to both sides:
8y = 56
Divide both sides by 8:
y = 7
Answer:
The fraction of the book Omarion read over the weekend=3/5
Step-by-step explanation:
Step 1
Determine the initial number of pages in a book that's remaining as follows;
Initial number of pages remaining=9/10 of the book
Step 2
Determine fraction of the book read over the weekend as follows;
fraction read over the weekend=fraction of the remaining read×initial number of remaining pages read
where;
fraction of the remaining read=2/3
initial number of remaining pages read=9/10
replacing;
fraction read over the weekend=(2/3)×(9/10)=3/5
The fraction of the book Omarion read over the weekend=3/5
