You would divide 192 by 6 to get y by itself
y=32
Answer: 12 3/8
10 1/2 + 10 1/2= 21
45 3/4 - 21 = 24 3/4
24 ÷ 2 = 12
Change the 3/4 into 8ths = 6/8
Divide that in half which gives you 3/8
So the length is 12 3/8
I think you have to subtract 60% and 80% which you get 20%
we know that
1) You have 
of a pie leftover after your party
2) Each
guest takes home 
of the leftover pie
To find the fraction of the original pie does each guest take home,
Multiply by
so
<u>Simplify </u>
Divide by 
both numerator and denominator
therefore
<u>the answer is</u>
Answer:
x² + 7x + 10 = 0
Subtract 10 from both sides
x² + 7x = -10
Use half the x coefficent (7/2) as the complete the square term
(x + 7/2)² = -10 + (7/2)²
note: the number added to "complete the square" is (7/2)² = 49/4
(x + 7/2)² = -10 + 49/4
(x + 7/2)² = 9/4
Take the square root of both sides
x + 7/2 = ±3/2
Subtract 7/2 from both sides
x = -7/2 ± 3/2
x = {-5, -2}
