Answer:
-25/42
Step-by-step explanation:
1. Multiply each equation so they end up with the same coefficient
2. Subtract your second equation from the first
3. Solve for one of the variables (I tend to solve an equation that only contains 2 variables if possible. So it would be if you have one question with x and y, solve for the easier one)
4. Substitute the variable you found in the least step into one of the other equations and find a second variable.
5. Substitute both variables you found into the last equation and there you should be left with x, y, and z :))
I hope this helped sksjsk if it didn’t I could write it out to hopefully help more :)
No, 6,500 is one hundred times as much as 65, because of the two zeros on the end. 100 and 6,500.
Let
x--------> the length side of the original square paper
we know that
<u>the area of the original square paper is equal to</u>
<u>the area of the remaining piece of paper is equal to</u>
therefore
<u>the answer is the option </u>
x2 − 2x − 120 = 0
Maria's organ systems interact to help keep her safe Nervous system, Respiratory system, Endocrine System, Integumentary System and Muscular System.
<h3>What are the organ systems?</h3>
The organ systems is the system of body which consist of different organs of the body. These organs help to work the body freely.
Maria is camping when she starts to smell smoke. She turns on her radio, to get the news that a forest fire is heading her way. The organs which help her to keep safe from fire are listed below:
- Nervous system- It helps to react the body against the hazard.
- Respiratory system-This organ system help Maria to keep breath with increasing the breathing rate.
- Integumentary System-This system help to protect her inner body from external environment.
- Endocrine System- It will help to maintain energy level.
- Muscular System-This system will help to run and do physical task in the fire.
Thus, Maria's organ systems interact to help keep her safe Nervous system, Respiratory system, Endocrine System, Integumentary System and Muscular System.
