139b + 1.29b = 50.73
2.49m + 2.69m = 51.63
Answer:
slope = - 3
Step-by-step explanation:
y = mx + b where m = slope
In this case y =-3x + 8, slope m = -3
Answer:
48 Units
Step-by-step explanation:
Use the Pythagorean theorem to make two right triangles.
Ex= Base is cut in half to make two 9 unit bases
Then count the units from the half point.
Ex= 12 units long
Then use Pythagorean theorem to find one side of the 9-12 right triangle
Ex= 9^2+12^2=c^2
After finding that c=15 units, add all the sides back together
Ex= 18+15+15=48
