We know that
1 Kg is equals to--------------> 1000 g
so
X Kg------------------------> 300 g
X=300/1000------> x=0.30 Kg
if 2 Kg cost--------------> <span>£7.20
0.30 Kg-------------> X
X=0.30*7.20/2------> x=1.08
the answer is
</span>£1.08
Answer:
y = -9x + 12
Step-by-step explanation:
first find the slope
m= <u>3 - 12</u>
1 - 0
m = -9
y = mx + b
y = -9x + 12
(the 12 is the y intercept and is given in the question so there is no need to solve for it)

Step-by-step explanation:
Answer:
100
Step-by-step explanation:
.15x + 23 = .10x + 28
Answer:
I think the answer is... C. No Solution because if you plug in those points for x & y, it has no solution... It is false... so yeah... I'm really really sorry if I'm wrong...
Step-by-step explanation:
x -2y = 4 - 3x + 6y = 12
-2 - 2(4) = 4 - 3(-2) + 6(4) = 12
-2 - 8 = 4 6 + 24 = 12
-10 = 4 30 = 12
x -2y = 4 - 3x + 6y = 12
0 - 2(-2) = 4 - 3(0) + 6(-2) = 12
0 + 4 = 4 0 - 12 = 12
4 = 4 - 12 = 12
