Joe, Quon and lulu have a lower ration and the others have a greater ratio
The answer is the first choice, "y=-3x."
When you multiply the x-inputs by -3, they come out as the values in the y-input section.
1·-3=-3
3·-3=-9
-2·-3=6
Ok the first one.....No solution
The word problem......1.90
and the last one......U=4
I hope this helps!!! :)
M equals 3x+21 because you add 2x+1x=3x.then you add 14+7=21.then you combine them together to get 3x+21
just looking at the density of the sand and gold you can see the gold is heavier but here are calculations for proof:
calculate volume of cylinder
V=PI x r^2 x h = 3.14 x 3.8^2 x 22 = 997.52 cubic cm
now calculate mass of the gold and the sand
gold = 19.3 x 997.52 = 19252 grams (19.25 kilograms)
sand = 3.00 x 997.52 = 2992.56 grams (2.99 kilograms)
so yes he set the alarm off
