Answer:
Alyssa’s lemonade recipe
Step-by-step explanation:
→ Work out how much lemons is needed per gallon for Alyssa’s lemonade recipe
9 lemons = 2.5 gallons
(÷ 2.5) = (÷ 2.5)
3.6 lemons = 1 gallon
→ Work out how much lemons is needed per gallon for Brian’s lemonade recipe
12 lemons = 4 gallons of water
(÷ 4) = (÷ 4)
3 lemons = 1 gallon of water
→ Now compare
Alyssa’s lemonade recipe ⇒ 3.6 lemons = 1 gallon
Brian’s lemonade recipe ⇒ 3 lemons = 1 gallon of water
Answer:
![p=-7/2=-3.5](https://tex.z-dn.net/?f=p%3D-7%2F2%3D-3.5)
Step-by-step explanation:
So we have the equation:
![9-4(2p-1)=41](https://tex.z-dn.net/?f=9-4%282p-1%29%3D41)
First, let's subtract 9 from both sides:
![-4(2p-1)=32](https://tex.z-dn.net/?f=-4%282p-1%29%3D32)
Divide both sides by -4:
![2p-1=-8](https://tex.z-dn.net/?f=2p-1%3D-8)
Add 1 to both sides:
![2p=-7](https://tex.z-dn.net/?f=2p%3D-7)
Divide both sides by 2:
![p=-7/2=-3.5](https://tex.z-dn.net/?f=p%3D-7%2F2%3D-3.5)
And we're done!
