Answer:
y = -2/3x + 4
Step-by-step explanation:
2x + 3y = 12
3y = -2x+12
y = -2/3x + 12/3
y= -2/3x + 4
D. the number of phone calls.
One day there could be 80 phone calls and the next there could be 2. It is continuously random.
The family would buy the three pairs of shoes for $26.31 because you have to divide $52.62 in half since they bought half the amount of pairs of shoes that are given in the sale.

If the numerator is greater than or equal to the denominator of a fraction, then it is called an improper fraction. In that case, you could convert it into a whole number or mixed number fraction.
26/7 = 3 5/7
