Answer:

The approx. length of a reptile that has a mass of 20.5 grams is 75

Step-by-step explanation:

y=0.3x-2

Okay so the value for y in the equation would be 20.5 so plug the value of y into the equation:

20.5 = 0.3x-2

And we are wanting to find the approximate length of a reptile that has a mass of 20.5 grams.

1. 20.5=0.3x-2

2. 20.5=\frac{3x}{10} -2

20.5=\frac{3x}{10} + \frac{10(-2)}{10}

I would give you the whole explanation, but to save time the answer is x=75

Hope this helped you

Please give 5 stars and a thank you if correct! Have a good day!
