3x - 2x + 4 = 5x - 4x - 8
First, let's focus on the left side of the problem (3x - 2x + 4). Let's subtract 3x - 2x which will get us 1, and since a variable by itself is considered 1, we can just put the variable.

Second, now let's focus on the right side of the problem (5x - 4x - 8). Subtract 5x - 4x to once again get 1. Replace it with the variable and leave the rest.

Third, we can now cancel out x on each side. This will leave us with 4 = -8, which is false, meaning that there is no solution to this problem.
Answer:
450 m²
Step-by-step explanation:
Area of a circle: 
r is radius and we need to divide the diameter value by 2 to obtain the radius
= 24 / 2 = 12m
Area of a circle = 
= 452.57
≈ 450 m²
The answer is the third option.
m = 7.5h
The h value multiplied by 7.5 will give you the m value.
7% into decimal is 0.07
0.07 x $150,000
= $10,500
