The amount of gas consumed by first and second car were 20 gallons and 15 gallons respectively.
Explanation
Suppose, gallons of gas were consumed by the first car.
As the total gas consumption in one week is 35 gallons, so the amount of gas consumed by second car will be: gallons.
The first car has a fuel efficiency of 35 miles per gallon of gas and the second has a fuel efficiency of 15 miles per gallon of gas.
So, the distance traveled by the first car in gallons of gas miles and the distance traveled by the second car in gallons of gas miles.
Given that, the two cars went a combined total of 925 miles. So, the equation will be.....
So, the amount of gas consumed by the first car is 20 gallons and the amount of gas consumed by the second car is: (35 - 20) = 15 gallons.
The solution of the expression twice a number, minus 13 in numeral form, is 2x-13
A collection of constants, variables or numbers connected using one or more arithmetic operator is called an expression
Example = 4y, 3x+4.
The given expression in numeral form is represented as:
Assume, the unknown variable be x.
The twice of the number is 2x.
Further, subtracting 13 from the 2x results in 2x-13.
Thus, the solution of the expression twice a number, minus 13 in numeral form is 2x-13.
