Answer:
x = 3
y = 4
hey, I am not 100% sure of the certainty of my answers, I am using what I remember about that topic but I do not know if it is right or wrong, I hope I have helped you, I did what I could.
Step-by-step explanation:
-3x + 2y = 23
5x + 2y = -17
X solution:
(you cancel the y)
-3x = 23
5x = -17
(you combine all the values above with those below)
2x = 6
(solve the ecuation normaly)
x = 6/2 = 3
Y solution:
(you replace the x)
-3(3) + 2y = 23
5(3) + 2y = -17
-9 + 2y = 23
15 + 2y = -17
(you combine all the values above with those below)
6 + 4y = 6
(solve the ecuation normaly)
4y = 0
y = 4
(I do not really know if the answer here is 0 or 4 since when passing the 4 to divide it would be 0/4 and I do not understand very well how that is solved)
Subtract 9 from both sides. Then you have -14=c/4. Multiply the number by 4. You now have -56=c. :)
Answer:
3.5
Step-by-step explanation:
Changed them to decimals ( top number divided by the bottom will get you the decimal) and I got the answer. message me if you need more help
Answer:
-12r2-9r-6
Step-by-step explanation:
-distribute the subtraction symbol to the second group of numbers
-(9r2+7r+2) = (-9r2-7r-2)
-then combine each term together (-3r2-2r-4)+(-9r2-7r-2)
= -12r2-9r-6
HOPE THIS HELPS!!
I believe the answer would 5 blocks
If you go 3 blocks East and 4 north, they are like the straight sides of a triangle, so to find the diagonal distance, or the shortest distance, you would find the diagonal side of a triangle it is
A squared + B squared = C squared
So 3x3 = 9
And 4x4 = 16
16+9=25
And the square root of 25 is 5
Please correct me if I am wrong and have a good day
