Answer:

38.13 = 12 +4.75h

5.5 hours

Step-by-step explanation:

(a) The charge (c) for renting a bike for h hours is ...

c = helmet charge + hourly charge × hours

c = 12.00 +4.75h

To find the number of hours when the charge is 38.13, we would use the equation ...

38.13 = 12.00 +4.75h

__

(b) To solve this 2-step linear equation, we first subtract the constant

26.13 = 4.75h

then we divide by the coefficient of the variable.

26.13/4.75 = h ≈ 5.5

Amanda rented the bike for 5.5 hours.

<em>Additional comment</em>

The result of the division is a long repeating decimal that starts off 5.50105263.... The instructions tell you to round this to the nearest tenth: 5.5. It helps to follow instructions.

Evaluate the expression for x = 4: 6+ (10 - x)2 - 20

Liono4ka [1.6K]

6 + (10 - 4)2 - 20 = 6 + 12 - 20 = 18 - 20 = -2

Assuming that the two in the middle of the expression is multiplied by (10 - x) the answer would be -2. I apologize if I did not read your question right.

Answer: Answer is in the step.

Step-by-step explanation:

The student made a mistake by identifying the maximum point by the x coordinate value of the vertex. Minimum or maximum points are determine using the y coordinate value.The student can determine the difference between a maximum and minimum by identifying the y coordinate of the vertex.
