We have been given that Jonathan is using the microscope in lab. He saw a chain of bacteria that was 10 millimeters long. We are asked to find the length of chain of bacteria in centimeters.
We know that 1 millimeter is equal to 0.1 centimeter.
To convert 10 milllimeters into centimeters, we will multiply 10 by 0.1.



Therefore, the chain of the bacteria is 1 cm long.
Answer:

Step-by-step explanation:
Let height of a banner be
, then we know that this is
of the length
of the banner; so we have
.
Now we can rearrange this equation to solve for the length of the banner given it's height:

So there we have it!
If the banner is 5 ft tall, then it's length will be:

First, we should add 1 to both sides to isolate the variable:
3x = 12
Now that x is isolated, we divide by 3:
x = 4
Answer:
let the numbers be x and y then by given conditions:
x + y = 10 ….. eq 1
and
xy = 9….. eq 2
from eq 2. y = 9/x
put this in eq. 1
x + 9/x = 10
x + 9= 10x
x = 1
now,
xy = 9put value of x
y = 9
