A culture started with 5000 bacteria. after 7 hours, it grew to 6500 bacteria. predict how many bacteria will be present after 1
9 hours. round your answer to the nearest whole number
1 answer:
6500=7x+5000
6500-5000=7x+5000-5000
1500=7x
1500/7≈214
x≈214
y=19·214+5000
y=9066
answer=9066 bacteria

144.74 pounds, I rounded the answer. to get this you would divide 55 by .38 .
m∠BEC=(1/2)(mBC + mAD)
110 = (1/2)(x+97)
220 = x+97
x=220 - 97
x= 123⁰
3x² (6x² - 13x - 5) =
3x² (2x - 5) (2x+1) .
