Those ratios are not equivalent because 240 divided by 16 is 15 and 560 divided by 28 is 20.
5x-3=21-x
6x=24
X=4
You simply have to isolate the variable and then divide by 6 so that x is completely alone.
Find the volume of each tank by multiplying the length by the width by the height:
Terry: 14 x 12 x 10 = 1680 cubic cm.
Bob: 13 x 15 x 8 = 1560 cubic cm
Terry’s aquarium is larger and can hold more water.
