Answer: 8 units
Step-by-step explanation:
Set this up as an equation with a variable for turtles. Count up the other side of the scale (without turtles). Add up the three 1s and the 4 to get 7. Then add up all four 7s. This will get you with an equation 3t+4=28.
To solve this, first subtract 4 from both sides to get 3t=24. Now divide both sides by 3. 24/3=8. Each turtle weighs 8 units.

Answer:
h(-8)=-8
Step-by-step explanation:
Since we are finding h(-8), we plug -8 into the equation:
h(-8)=((-8)²+3(-8))/(4(-8)+27)
h(-8)=(64-24)/(-32+27)
h(-8)=40/-5
h(-8)=-8
Therefore, h(-8)=-8, which means your answer is correct!
