Hag fish have a mostly cartilaginous skeleton. How do they get enough force to tear flesh from the grey whale carcass?

Once a firm hold is established on the prey, the hagfish ties and untied a knot within its own body to create a ripping force. It then burrows into dead carcasses exposing its skin to the nutrient-rich decomposing matter while eating away at the dead animal's inside. It leaves the skin and bones behind.

Explanation:

there are 35 white marbles

step-by-step explanation:

y- yellow marbles

4y + 5 = 45

subtract 5 from both sides

4y = 40

divide for from both sides

y = 10

plug in 10 to get 40 yellow marbles then subtract by 5 to get 35 marbles

thus there are only 10 yellow marbles
