Answer:
Step-by-step explanation:
Remember you can do anything to an equation as long as you do it to both sides
2b+3c=14
minus 3c both sides
2b=14-3c
divide both sides by 2
The new shower head dispenses 3 gallons of water per minute, as shown in the equation y = 3x.
So, 3 x 8 = 24.
Then, to find out how much he saves each day, you would find how much he used before,
11 x 8 = 88
Next we want to see how much Nathan saved, so we subtract the total,
88 - 24 = 64
Nathan saved 64 gallons.
Month 1
Sister 1; 60/ Sister 2; 60
Month 2
Sister 1; 80/ Sister 2; 60
Month 3
Sister 1; 100/ Sister 2; 100
On month 3 the should both have $100 in their accounts.
The number that is missing is 83
