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.
-12x = 12x
Start by moving all the terms with the variable you want to solve for on one side of the equation and the rest on the other side of the equation.
We will move 12x to the left side of the equation by subtracting 12x from both sides. Now your equation should look like:
-24x = 0
Isolate the variable x by dividing both sides by -24. Everything divided by 0 is equal to 0, so that means x will be equal to 0.
x = 0
Your answer is x = 0.
Step-by-step explanation:
Hello there!
Just double the given sides!
(18*2)+(12*2)=60 cm.
There you are!

Grace weighed 167 pounds before she started her exercise program.
Step-by-step explanation:
Given,
Weight lost by Grace = 45 pounds
Weight of Grace after exercise weeks = 122 pounds
Let,
x represents the weight of Grace before she started the exercise program.
Loss means subtraction, therefore,
We will subtract the lost weight from original weight.
Original weight - Weight lost = Weight after exercise weeks

Adding 45 on both sides

Grace weighed 167 pounds before she started her exercise program.
