16/8 =2
24/8 =3
8 packets
each packet will have 2 pencils and 3 erasers
Ok let’s solve it
5(x-2)^2-20=0
first let’s foil (x-2)
5(x^2-4x+4) -20=0
now distribute the 5
5x^2 -20x +20 -20 = 0
combine like terms
5x^2-20x=0
take the gcf
5x(x-4)=0
x=0, 4
solutions are (4,0) and (2, -20) because the original vertex form a(x-h)^2+k
Answer:
C
Step-by-step explanation:
So the lion weighs more than the ant right?
And we wish to figure out how much greater the lion's weight is compared to the ant's weight.
So only thing we have to do is divide.
![\frac{1 * 10^5}{2*10^-3} = \frac{10^5}{2*10^-3} = \frac{10^8}{2} = 50000000 = 5 * 10^7](https://tex.z-dn.net/?f=%5Cfrac%7B1%20%2A%2010%5E5%7D%7B2%2A10%5E-3%7D%20%3D%20%20%5Cfrac%7B10%5E5%7D%7B2%2A10%5E-3%7D%20%3D%20%20%5Cfrac%7B10%5E8%7D%7B2%7D%20%3D%20%2050000000%20%3D%205%20%2A%2010%5E7)
Answer:
(A) a=1,b=5,c=9
Step-by-step explanation:
We want to simplify
for values of a, b and c which satisfies: ![a\dfrac{b}{c}](https://tex.z-dn.net/?f=a%5Cdfrac%7Bb%7D%7Bc%7D)
Converting our result to mixed fraction
![\dfrac{28}{18}=1\dfrac{10}{18}=1\dfrac{5}{9}\\a=1,b=5,c=9](https://tex.z-dn.net/?f=%5Cdfrac%7B28%7D%7B18%7D%3D1%5Cdfrac%7B10%7D%7B18%7D%3D1%5Cdfrac%7B5%7D%7B9%7D%5C%5Ca%3D1%2Cb%3D5%2Cc%3D9)
