Answer:

• In consideration with the general equation of a line:

${ \rm{y = mx + b}}$

→ m is the slope

equation given:

${ \rm{C = 9 + 0.50t}} \\ \\ { \rm{C = 0.50t + 9}}$

• from comparison, m is 0.50

Answer: slope is 0.50

Shane has 1/2 pound of cheese to make 4 sandwiches. He wants to use the same amount of cheese in each sandwich. What fraction of

anastassius [24]

Answer:

The fraction of one pound of cheese to be used in each sandwich is 1/8

Step-by-step explanation:

Here, we have a question that requires the method of dealing with the division of fractions.

To divide a fraction by a whole number, we multiply the denominator of the fraction by the whole number as follows;

$\frac{x}{y} \div z =\frac{x}{y\times z}$

Quantity of cheese Shane has = 1/2 pound

Number of sandwiches to be made = 4

Amount of cheese per sandwich = 1/2÷4 = 1/8.

Question 17 (5 points)

Elden [556K]

Answer:

The pet sitter babysat his dog for 3 hours.

Step-by-step explanation:

You know that a pet sitter charges $ 20 for supplies and $ 10 per hour of service, represented by the equation C = 10*n + 20, which describes the total cost she would charge for n hours of service.

The pet sitter charges a customer $ 50 for his service, so C has a value of $ 50.

Replacing:

50=10*n+20

Solving:

50 - 20= 10*n +20 -20

30= 10*n

30÷10= n

3= n

The pet sitter babysat his dog for 3 hours.

Option: step 2.

Because the student divided only the right side by 2. If you divide one side by a number you have to do the same with the other side to maintain the equality.
