To find out how much substance M was added, we need to solve the equation:
13.93 + M = 18.0
To isolate M, we can subtract 13.93 from both sides of the equation:
M = 18.0 - 13.93
Simplifying the right side:
M = 4.07
Therefore, Dr. Burroughs added 4.07 units of substance M to the experiment.
13.93 + M = 18.0
To isolate M, we can subtract 13.93 from both sides of the equation:
M = 18.0 - 13.93
Simplifying the right side:
M = 4.07
Therefore, Dr. Burroughs added 4.07 units of substance M to the experiment.

To solve the equation "Five times what number + 10 equals 20," we can follow these steps:
1. Let's assume the unknown number is represented by the variable 'x.'
2. We can translate the given information into an equation: 5x + 10 = 20.
3. To isolate the variable, we will subtract 10 from both sides of the equation: 5x + 10 - 10 = 20 - 10.
4. Simplifying both sides gives us 5x = 10.
5. Finally, we divide both sides of the equation by 5: 5x/5 = 10/5.
6. Simplifying further yields x = 2.
Therefore, the number in question that satisfies the equation is 2.

To find out how many stamps Jaylin has, we can set up the following equation based on the given information:
5x - 10 = 275
Where 'x' represents the number of stamps Jaylin has.
To solve for 'x', we will follow these steps:
1. Add 10 to both sides of the equation:
5x - 10 + 10 = 275 + 10
5x = 285
2. Divide both sides of the equation by 5:
5x/5 = 285/5
x = 57
Therefore, Jaylin has 57 stamps.
5x - 10 = 275
Where 'x' represents the number of stamps Jaylin has.
To solve for 'x', we will follow these steps:
1. Add 10 to both sides of the equation:

To divide -3/17 by -2/3, we need to follow the rule of division for fractions:
When dividing fractions, we invert (flip) the second fraction and multiply.
So, let's calculate:
(-3/17) รท (-2/3) = (-3/17) * (3/-2)
Now, we can simplify the multiplication:
= (-3 * 3) / (17 * -2)
= -9 / -34
When we have a negative number divided by a negative number, the result is positive. Therefore:
= 9/34
Hence, -3/17 divided by -2/3 equals 9/34.
