Answer:
b = 13
Step-by-step explanation:
the value of the discount is a constant, while the total cost of the books is a variable because it depends of the purchase
We can write this equation
5b - 7 = 58
Solve it
1) add 7 at both members
5b -7 + 7 = 58 + 7
5b = 65
2) divide both membera by 5
b = 13
Answer:
The diameter of the bacterium is 4.05 times the diameter of the plant cell
Step-by-step explanation:
The given parameters both represent diameters
Plant Cell P = 1.26m
Bacterium B = 5.1m
First write out both expressions:
P = 1.26
B = 5.1
Divide B by P
5.1 / 1.26 = 4.04762 Round to 4.05
Multiply both side by P
P * B/P = 4.05 P
B = 4.05 P
This shows that the diameter of the bacterium is 4.048 times the diameter of the plant cell.
