Jenny's company has 15 trucks in two different sizes. There are small trucks with 6 wheels and large trucks with 12 wheels. Her company needs to inspect the 108 wheels of all of the trucks. How many large trucks does the company have?

Answer: 9

Step-by-step explanation:

The company has a total of 3 big trucks.

An algebraic expression is a combination of terms both variables and constants. We can write the examples of algebraic expression as -

2x + 3y + 5

5x + 4y + 1

Given is that Jenny's company has 15 trucks in two different sizes. There are small trucks with 6 wheels and large trucks with 12 wheels. Her company needs to inspect the 108 wheels of all of the trucks

We can write the system of equations as -

s + b = 15

6s + 12b = 108

6(15 - b) + 12b = 108

90 - 6b + 12b = 108

18 = 6b

b = 4

Therefore, the company has a total of 3 big trucks.

A local school needs to paint the floor of its theater room, where the length of the floor, x, is at least 12 feet. The width of the floor is 4 feet less than the length. It will have a stage and a closet, and the remaining area of the floor will be painted. The dimensions are shown in the diagram:

rectangle with length of x ft and width of x minus 4 ft, right triangle inside labeled stage with height of x minus 4 ft and base of 6 ft, rectangle inside labeled closet with length of 7 ft and width of 2 ft, the rest of the rectangle is labeled floor

Let A represent the painted area, in square feet, of the floor. Choose the correct equation to solve for area (A).

A = x(x − 4) + 0.5(6)(x − 4) + 2(7)
A = x(x − 4) − 0.5(6)(x − 4) − 2(7)
A = x(x − 4) − (6)(x − 4) − 2(7)
A = x(x − 4) + (6)(x − 4) + 2(7)
