Answer:

Mr. Reed DATA:

rate = 40 mph ; time = x hrs ; distance = 40x miles

-----

Mrs. Reed DATA:

rate = 60 mph ; time = x - 3.5 hrs ; distance = 60x - 210 miles

Equation:

40x = 60x -210

-20x = -210

x = 10.5 hrs

x-3.5 = 7 hrs (Mr. Reed's time)

The product of a number, x, and 3 is six more than the product of the number and 2.
Pavel [41]

Answer:

  • 3x = 6 + 2x

Step-by-step explanation:

The word "product" defines multiplication between two numbers. Those numbers are x and 3. The word "is" defines the "equal sign". The word "more" defines addition. Now, using these definitions, let's create an equation.

  • => (3 × x) = 6 + (2 × x)
  • => 3x = 6 + 2x

Hence, Option C is correct.
