Answer:

A. When x = 3, both expressions have a value of 30.

Step-by-step explanation:

The first expression is 4(x+3)+2x

The second expression is 6(x+2).

When we substitute x=3 into the first equation, we get:

4(3 + 3) + 2(3) = 4 \times 6 + 6 = 24 + 6 = 30

When we substitute x=3 into the second expression we get:

6(3 + 2) = 6(5) = 30

This proves that the two expressions are equivalent.

The correct choice is A

A taxi driver wrote a formula to represent the mileage and fee for his last customer. He wrote the equation 3.00 + 0.50 m = 9.50
Vsevolod [243]

Answer: The sum of three dollars and the product of 50 cents times the number of miles is nine dollars and fifty cents.

Three dollars plus $0.50 times the number of miles is equal to nine dollars and fifty cents.

Step-by-step explanation:

Hi, to answer this question we have to analyze the equation given:

3.00 + 0.50 m = 9.50

Where m is the number of miles.

The equation states that the fixed fee charged (3.00) plus the product of the value of each mile traveled (0.50) and the number of miles traveled (m); is equal to 9.50.

So, the correct statements are:

  • The sum of three dollars and the product of 50 cents times the number of miles is nine dollars and fifty cents.
  • Three dollars plus $0.50 times the number of miles is equal to nine dollars and fifty cents.

Feel free to ask for more if needed or if you did not understand something.
