Fourth one i think (the way u typed the q is confusing)
Answer:
(-4,1)
Step-by-step explanation:
Multiply first equation by 2
4x+6y=-10
Then subtract with second equation you get:
y=1
So put the value in first equation you get :
2x+3=-5
x=-4
650 because if you divide 585 by 0.9 then you get 650. This shows you what 585 is 90% of which means it is also 10% less than the answer of 650. I hope this makes sense
4 > 10 because this sign > is always the less sign and this < is greater
