If we start with 5 cells, and each cell divides in two every 15 minutes, how many total after 1 hour?

Step-by-step explanation:

5 x 2 = 10 = Fifteen Minutes (15)

10 x 2 = 20 = Thirty Minutes (30)

20 x 2 = 40 = Forty - Five Minutes (45)

40 x 2 = 80 = Sixty Minutes (60)

80 Cells

so what is the question

step-by-step explanation:

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
