Y=2x is an equation that passes through those points
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. 

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!
"Calculate the square root of 10 (√ 10) to 4 decimal places.<span>Find the perfect square number closer to 10. 32 = 9 and 42 = 16, so take 3.Divide 10 by 3. 10÷3 = 3.33 (you can round off the answer)Average 3.33 and 3. ( 3.33 + 3)÷2 = 3.1667."

50% because when you take out the first marble witch is probably blue since there are more blue you would have 2 blue and 2 green so the chance would be 50%
