Question

write a mathematical sentence that expresses the information given below. use g as your variable name. if necessary: type <= to mean ≤ or >= to mean ≥. the number of gallons of gas that were in the tank plus 7 more adds up to 12 gallons.

Explanation:

Step1: Analyze the description

Let \( g \) be the number of gallons of gas in the tank. "The number of gallons of gas that were in the tank plus 7 more" can be written as \( g + 7 \).

Step2: Set up the equation

Since this sum "adds up to 12 gallons", we set up the equation \( g+7 = 12 \).

Answer:

\( g + 7=12 \)
