Step-by-step explanation:
72x.20= 14.4

I'm pretty sure this is right
Well. I can't see the picture. But it would be decreasing at a rate of 4 so pick a point on the any line move over to the right one, then down four. And for the y intercept the line would intersect the y axis at positive one. Sorry if that's confusing
X = 1/3 yz
3x = yz
y = 3x/z
1/100 of a metre, as 100cm make 1m
6 - a = 1/3(9a - 18)
6 - a = 3a - 6
-a - 3a = -6 - 6
-4a = -12
a = -12/-4
a = 3..........one solution
