The Solution is 5.68 x 10^5
Answer:
25%
Step-by-step explanation:
Answer: 1.33-inch wheels
Step-by-step explanation:
The scale factor is 1 : 12. (i.e 12 inches on the actual is represented by one unit on the scale model)
So, If the actual car has 16-inch wheels,
The size of the wheels on the scale model will be 16-inch / 12 = 1.33-inch
Thus, Thom's car will have 1.33-inch wheels
x = 8
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-4x' to each side of the equation.
72 + 9x + -4x = 112 + 4x + -4x
Combine like terms: 9x + -4x = 5x
72 + 5x = 112 + 4x + -4x
Combine like terms: 4x + -4x = 0
72 + 5x = 112 + 0
72 + 5x = 112
Add '-72' to each side of the equation.
72 + -72 + 5x = 112 + -72
Combine like terms: 72 + -72 = 0
0 + 5x = 112 + -72
5x = 112 + -72
Combine like terms: 112 + -72 = 40
5x = 40
Divide each side by '5'.
x = 8
