Answer:
B i think
Step-by-step explanation:
i think its B because all the other ones don'e look right. hope its correct. :)
There are many equations that has a constant of
proportionality, might want to make it more specific.
First multiply 40 and 10 to get 400. Then multiply 400 by 8 to get 3,200.
Your answer would be: 3,200
It takes 5 minutes per square foot (400/180=5) and so 5 minutes per square for 720 squares: 720x5=3,600. 3,600 minutes is equivalent to 60 hours so it takes him 60 hours.
Remember to follow PEMDAS, and to only combine terms with like variables.
First, distribute the 2 to all terms within the parenthesis:
2(2p + 4t) = 2(2p) + 2(4t) = 4p + 8t
3 + 4p + 8t, or (D), is your answer choice, for it cannot be simplified anymore.
