Well, you can put various math problems into one. Equations can also show more information easier than writing many problems. Hope this helps, and keep learning!
Answer:
The solution to the system of equations is:
Step-by-step explanation:
Given the system of equations
solving the system of equations
solve for y
Divide both sides by -23
Divide both sides by 10
Thus, the solution to the system of equations is:
I drew this by hand. sorry I it does not help.
Answer:
D. 25%
Step-by-step explanation:
There are two ways that I do this. Both of them are probably not what your teacher tells you, but hey, I got the right answer.
The first method is to go through the answers and do 14 x .10, 14 x .20, and so on until you get 3.50.
The second method is to do 14/3.5, which equals 4. This means 14 can be broken up into 3.50 four times. So, 3.50 is 1/4 of 14. What is 1/4 of 100%? 25%.
Your answer would be 12x + 8 because there are 4 sides to a square and they are all 3x + 2, so you would need to multiply 3x + 2 by 4 which you can do by expanding brackets which gives you 4(3x + 2) and thus when you multiply it out you get 12x + 8. I hope this helps!
