8x = 56
8x + 16 = 40
x = 3
8x = 24
x = 7
8x – 16 = 40
8(x – 2) = 40

The car travelled a distance of 36.15 miles in 1 hour. The car travelled a distance of 12.05 miles in 1 gallon of gas.
The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
It is given that a car traveled at a constant speed for 4 hours and covered 144.6 miles and also it used 12 gallons of gas to travel this distance.
It took 4 hours to travel a distance of 144.6 miles.
For 1 hour at constant speed, the car will travel 144.6/4 miles .
∴ For 1 hour at constant speed the car travels 36.15 miles.
For 12 gallons of gas, the car travels 144.6 miles.
For 1 gallon of gas, the car travels 144.6/12 = 12.05 miles
∴ For 1 gallon of gas, the car travels 12.05 miles.
Thus the car travelled a distance of 36.15 miles in 1 hour. The car travelled a distance of 12.05 miles in 1 gallon of gas.

x<-5
If I read the question correctly and x stands for a variable, and not multiplication, you can multiply each value by 10 to get whole numbers (or not, but whole numbers are easier to work with, and you get the same answer either way, I checked). This gives you
-4x -12>8
First you want to isolate x by adding 12 to both sides and getting. -4x>20. Then you divide both sides by -4, but when doing so, remember that when you divide by a negative number, you need to flip the sign. So then your answer is x<-5.

This is an algebraic expression.The answer is 10,because 45-10=35.
The area of rectangle ABCD is 104 square units.
The area of the space occupied within the perimeter of a rectangle is called the area of a rectangle. It is calculated by finding the product of the length and breadth of the rectangle.
The perimeter of a rectangle is the sum of its four sides. Hence, Perimeter of Rectangle = 2 (Length + Width) units. The area of a rectangle is defined as a product of length and width. It is expressed in terms of squareunits.
