Answer:
Yes it is.
Step-by-step explanation:
When we mix Fe(iron) to CuSO⁴ (Copper sulphate), Iron removes copper from CuSO⁴ and makes FeSO⁴. This happens because iron is more reactive than copper. We cannot remove iron from this solution now until any stronger element is added.
Answer:
3 AND 5
Step-by-step explanation:
LET THE TWO NUMBERS BE X AND Y
THEN
X + Y = 8 …….1
X – Y = 2 …… 2
WE SOLVE SIMULTANOUSLY
SUBTRACTNG EQATION 2 FROM 1
X – X + Y – (-Y) = 8 – 2
Y + Y = 6
2Y = 6
DIVIDING EACH TERM BY 2
2Y/2 = 6/2
Y = 3
THEN PUTTING Y = 3 IN EQUATION 1
X + 3 = 8
X = 8 – 3
X = 5
Answer:
solution: -3<w<6
interval notation: (-3,6)
Step-by-step explanation:
The coordinates are (-3,6) all you have to do is put them on a graph! Hope this helps!
Parallel lines- lines that can go on and on without touching each other.
X=$12.50
y=$6.25
$12.50x+$6.25y (> and =) $1500
