Which situation best represents the following equation 15+.15x<25+.05x
Goryan [66]

Answer:

x<10

Step-by-step explanation:

First, we want to move all of our like terms to one side. In the inequality, the variable x on one side and our whole numbers on the other.

To do this you have to cancel out 0.5x on the right side. So you need to subtract 0.5 from both sides.

This leaves you with 15+x<25. Subtract 15 from both sides which leaves you with x<10

Hope this helps :)

castortr0y [4]

Answer:

Kindly check explanation

Step-by-step explanation:

Given the dimension of the dog pen = 30 ft by 40 ft.

Using the knowledge of geometry, that know that a rectangle has been built, the area of the pen should be :

Area of rectangle = Length * width

Area = 40 * 30

Area = 1200 ft²

Perimeter of rectangle = 2(Length + width)

Perimeter = 2(40 + 30)

Perimeter = 2(70)

Perimeter = 140 feets

Hence, area of the pen should be 1200 ft² and its perimeter or fencing should measure 140 feets
