Y coordinate on solving both equations comes out to be 0
-2x+3y=-6
3y = -6+2x
put the value of 3y in equation 2nd
5x-2(-6+2x) =15
5x+12-4x = 15
x=3
put value of X in 3y = -6+2x
3y = -6+2*3 = -6+6 = 0
thus y = 0
Answer:
36
Step-by-step explanation:
3 * 12 = 36
if there are 12 girls and 3 times more wore dress then 3 times 12 is 36.
Answer:
60 degrees
Step-by-step explanation:
The angles all have to add up to 180, so you can do

10000:100*11=1100 income per year
21000-10000=11000 need to have income
11000:1100=10 years will pass time
change into improper fraction then do the problem then turn back into mixed number
