6 students were in class because the 5 represents on how many groups you need to have
Use elimination
-x - y = -9
x - y = 3
Add both equations
-2y = -6, y = 3
-x -(3) = -9
-x = -6, x = 6
Final answer: x = 6, y = 3
<span>t+u = 10
10u+t= 10t+u-54
Rearrange:
t+u=10
9t-9u=54
Simplify:
1st; t+u=10
2nd: t-u=6
Add 1st and 2nd and solve for t,as follows:
2t = 16
t = 8
Substitute in t+u=10 to solve for u:
8+u=10
u = 2
Original Number = 82</span>
Answer:
<u>2</u>
Step-by-step explanation:
Formula for slope is Y2-Y1/X2-X1
-3-3/-2-1= -6/-3
-6/-3 is 2
Well the square root of 72 is 8.485 and the square root of 45 is 6.708. hope this helps :)
