- 40 ≥ 8 b
switch sides:
8b ≤ - 40
divide both sides by 8 :
8b / 8 = - 40/8
refine:
b ≤ - 40 / 8
b ≤ - 5
hope this helps!
Answer:
The builder worked roughly 12 hours and the plumber worked around 13. The builder got paid 330.75 so just divide 28 by that to get 11.9... then add 330.75 and 106.75 (which will be 437.50) and divide the sum by 35 the get 12.5.
Step-by-step explanation:
Y -intercept (-1,0)
X- intercept(0,-3)
Area of the base is 21 square feet
<span>Pyramid Volume = (Area of the Base * Height) ÷ 3
</span>
84 = (21 * Height) / 3Height = 84 * 3 / 21
Height = 12 feet
