Step-by-step explanation:
A number divided by three can be three
The total rental cost is $120.
Let x be the amount each person pays and y be the total cost. Our first equation would be
4x = y.
The second equation would be
6(x-10) = y.
Since these are set equal to the same variable, we can use substitution:
4x = 6(x-10)
Using the distributive property, we have
4x = 6*x - 6*10
4x = 6x-60
Subtract 4x from both sides:
0 = 2x-60
Add 60 to both sides;
60 = 2x
Divide both sides by 2:
30 = x
This means each person pays $30 (in the first equation). 4(30) = 120 for y.
With 4 people, each person pays $30; with 6 people, each person pays 30-10=20.
By using the <em>area</em> formulae for triangles and rectangles and the concept of <em>surface</em> area of the <em>composite</em> figure is equal to 1108 square inches.
<h3>What is the surface area of the composite figure?</h3>
The <em>surface</em> area is the area of all faces of a solid. In this case, we must sum the areas of seven <em>rectangular</em> and two <em>triangular</em> faces to determine the <em>surface</em> area:
A = 2 · (0.5) · (12 in) · (9 in) + 2 · (11 in) · (20 in) + 2 · (5 in) · (20 in) + 2 · (5 in) · (12 in) + (12 in) · (20 in)
A = 1108 in²

Not sure what problem you mean, perhaps
4(3) + 4(6) = 4(3+6) = 4(9) = 36
Answer: 36
