Solve 10x + 75 = 150. Round your answer to the nearest hundredth.
A. x ¡Ö 1.63
B. x ¡Ö 1.56
C. x ¡Ö 1.75
D. x ¡Ö 1.88
10 x + 75 = 150 Substract 75 to both sides
10 x + 75 - 75 = 150 - 75
10 x = 75 Divide both sides by 10
x = 75 / 10 = 7.5
1.63
To solve the equation 10x + 75 = 150, you need to isolate the variable x. Here are the steps to solve it:
1. Start by subtracting 75 from both sides of the equation:
10x + 75 - 75 = 150 - 75
This simplifies to:
10x = 75
2. Next, divide both sides of the equation by 10 to isolate the variable x:
10x/10 = 75/10
This simplifies to:
x = 7.5
3. The answer, however, requires rounding to the nearest hundredth. Since 7.5 is already rounded to the nearest tenth, it does not need any further rounding.
The correct answer is x = 7.5, which is none of the options given (A, B, C, or D).
