Answers

Answer 1

Answer:

D. 3/19

Step-by-step explanation:

12/1 = 12

12/2 = 6

12/3 = 4

These are the only ones that make the equation true.

There are also only 19 numbers because they need to be less than 20 like the question indicated. Therefore, the answer is D.

Maria took a taxicab from her home to the theater
downtown. The taxicab company charges a flat fee of $5.00
plus $0.25 per mile. Which equation represents C, the total
cost of her ride, in terms of m, the length of the trip in
miles?

Answers

Answer:

the answer is #3

Step-by-step explanation:

the expression that represents C, the total cost of her ride, in terms of m, the length of the trip in miles is C = 5 + 0.25m.

What are mathematical operations?

The term "operation" in mathematics refers to the process of computing a value utilizing operands and a math operator. For the specified operands or integers, the math operator's symbol has predetermined rules that must be followed. In mathematics, there are five basic operations: addition, subtraction, multiplication, division, and modular forms.

Given this, Maria took a taxicab from her home to the theater downtown. The taxicab company charges a flat fee of $5.00 plus $0.25 per mile.

Since, C represents the total cost of her ride, in terms of m, the length of the trip in miles.

So,

Total cost = fixed cost + variable cost

In our case

Fixed cost = 5

and the variable cost = 0.25 per mile

For m miles variable cost = 0.25*m

Thus,

Total cost = 5 + 0.25*m

C = 5 + 0.25m

therefore, the expression that represents C, the total cost of her ride, in terms of m, the length of the trip in miles is C = 5 + 0.25m.

what are the y values of the equation y = 3x + 4 at x values -1, 0, 1, 2​

Answers

Answer:

-2; 1; 4; 7

Step-by-step explanation:

To solve for y, plug the x value in to the expression

y = 3(-1) + 1

y = -3 + 1

y = -2

When x = -1, y = -2

y = 3(0) + 1

y = 0 + 1

y = 1

When x = 0, y = 1

y = 3(1) + 1

y = 3 + 1

y = 4

When x = 1, y = 4

y = 3(2) + 1

y = 6 + 1

y = 7

When x = 2, y = 7
