Answer:
C= $1t + x
Step-by-step explanation:
So, an organic gallon of milk is 1 dollar more then regular so the equation starts at $1 + x.
But then buying the organic milk over time is t so you add that to the one dollar since it applies to the organic milk. Now the equation is $1t + x.
But now, the expression we wrote is equal to C so, now the equation is C=$1t + x
The answer to -2x+5=-3 is indeed , 4
900,000,000. move the decimal until you have a number between 1-10 so move it 8 times and you'll have 9×10^8
