Answer:
Step-by-step explanation:
For this exercise it is important to remember that:
1. The Addition property of equality states that:
If , then
2. The Subtraction property of equality states the following:
If , then
3. The Division property of equality states that:
If , then
4. The Multiplication property of equality states the following:
If , then
Then, having the following equation given in the exercise:
You need to solve for the variable "r" in order to find its value.
In order to solve for "r", you must apply the Addition property of equality adding 14 to both sides of the equation.
Therefore, you get the following solution:
Answer:
x=-9
Step-by-step explanation:
B is unnecessary here, so we can ignore it. The first thing we do in this equation is simplify by adding like terms. 5a-10a=-5a. So, the equation is now -5a=45. To solve a, we need it by itself. To do that, we undo the multiplication by diving both sides of the equation by -5. 45 divided by -5 is -9, and then we have x=-9.
Answer: Crossing over, or recombination, is the exchange of chromosome segments between nonsister chromatids in meiosis. Crossing over creates new combinations of genes in the gametes that are not found in either parent, contributing to genetic diversity.

Answer:
Step-by-step explanation:
This equation does not represent the situation because to find the fraction of the rain gauge we need to : divide the fraction of gauge filled by the raining fraction of an hour
But, Diego wrote the incorrect division equation so, it does not represent the current situation.
Now, to find the required division and multiplication equations :
