Answer:
x = 5
Step-by-step explanation:
First, we move all variables to one side of the equation. (Don't forget to change signs.)
9x - 8x + x = 7 + 3
Then, we simplify
x + x = 10
2x = 10
10 divided by 2 is equal to 5.
Therefore, x = 5

Answer:
10.429% exceed
Step-by-step explanation:
expected:
150x [100+40]/100=210 parents were expected on first night
210x60/100=126 parents expected on the second night
210+126=326 expected
percentage difference=
210+150=360
360/326 x 100=110,429%
110,429%-100%=10,429% exceed
1 hour = 60 min
0.5 hours = 60 * 0.5 = 30 min.
Answer:
Step-by-step explanation:

A cell of this bacterium in a nutrient-broth medium divides into two cells every 20 minutes.
Initial population = 71 cells
Doubles in 1/3 of an hour
, where t is the no of hours.
