Answer:
Robert's piece of wire is 5 feet long
and Maria's piece of wires is 7 feet long
Step-by-step explanation:
Suppose x and y are Robert's and Maria's piece of wires respectively.
We can write following equation using this statement "Half of Robert's piece of wire is equal to ⅔ of Maria's wire".
--------------(1)
The total length of their wires is 12 feet.
------------(2)
=> 
Substitute x=12-y in equation (1)




Put y=7 in equation (2)

8 are left handed bc 20% of its 40 is 0.2×40 =8
Step-by-step explanation:
Add 4 to both sides: 5e^3x = 35, or
Q=-1 :)
just solve for one variable of your choice in either function, in this case p then plug it into the other function to start solving for q.
