A6-inch personal pizza has 620 calories. determine the number of calories in the 14-inch pizza

186.666... calories for the 14-inch pizza.

Step-by-step explanation:

For the first pizza there's 13.33333333333... calories in 1 in.

For the second pizza you multiply 13.33333333333... by 14.

Equaling 186.6 repeating.

Have a great day!

Inconsistent

Step-by-step explanation:

We are given the equations;

0.3y=0.6x+0.3

1.2x+0.6=0.6y

Assuming we are required  to determine whether the system of equations are consistent or inconsistent  

We are going to use substitution

Making y the subject;

Equation 1: 0.3y=0.6x+0.3

Dividing both sides by 0.3

y = 2x + 1

Equation 2: 1.2x+0.6=0.6y

Dividing both sides by 0.6

y = 2x + 1

This means both equations are similar and we can't get a solution.

Therefore, the system of equations is inconsistent.
