Hello,
if the solution is infinite : the line x-3y=4 ,
so there is one line and not 2
==>x-3y=4 multiplied by 2
2x-6y=8=Q
Q=8
It is D, that is because A - C are not terminating decimals therefore only leaving D
Answer:
multiply by 2
Step-by-step explanation:
5x2=10
10x2=20
(180-x) + 18 + 30 + x/2 = 180
=> 180 + 48 - x + x/2 = 180
=> -x/2 + 48 = 0
=> x/2 = 48
=> x = 48×2 = 96°
Answer:
30
Step-by-step explanation:
200x.15=30
200-30=170
