Answer:
-35,35,0
Step-by-step explanation:
Let's organise our information :
Now let's add them together :
- x+xy²+x-xy²=250y-240y
- 2x=10y
- x=5y ⇒ y= x/5
Let's replace y by x/5 in the first equation :
- x+x*(x/5)²=250*(x/5)
- x+ (x∧3)/25 = 50x
- 49x-(x∧3)/25=0
- x(49-(x²/25))=0
- x=0 or 49-(x²/25)=0
- x=0 or 49= x²/25
- x=0 or x²=1225
- x=0 or x=
or x= -
- x=0 or x=35 or x= -35
so x=[0,35,(-35)]
The answer is g4 -2 hope this helps
Answer:
1:10 PM.
Step-by-step explanation:
If the meeting started at 12:15, it took 45 minutes to get to 1PM, however it lasted 10 minutes longer than that (55 minutes total). If 10 minutes of the meeting remains at 1PM, the meeting ended at 1:10PM. Therefore, 55 minutes after 12PM is 1:10PM.

40°
Step-by-step explanation:
∠ACB = ∠DCE ( vertically opposite angle )
Now...
a + 90° + 50° = 180° ( the sum of interior angle of triangle is 180° )
a + 140° = 180°
a = 180° - 140°
a = 40°
hence the value of a is 40°
