Isabelle takes the bus to work. The bus ride to work costs her $2.50 each time. She could buy a bus pass for a one-time fee of $15.00 and would then only pay $1.00 each time to ride the bus. How many times would she have to take the bus for the cost to be the same?

Answers

y = total cost

x = amount of times she takes the bus

Let's create two equations to model the data in the problem above.

y = $2.50x

y = $1x + $15

Now, let's set them equal to each other and solve for x.

$2.50x = $1x + $15

Subtract $1x from both sides.

$1.50x = $15

Divide both sides by $1.50

x = 10

She would have to ride the bus 10 times for the cost to be equal.

Answer:

10 Trips

Step-by-step explanation:

Create 2 algebraic Equations, X is the number of trips and y is the total cost. y=2.5x, and y=x+15. Set them equal to eachother and solve for X. 2.5X=X+15. Subtract X from both sides to get 1.5X=15. Divide by 1.5 to get 10. X=10, 10 Trips!

Answers

Answer: The slope is 6.

Step-by-step explanation:

One way to see the slope is to look at the graph and find places where the graphed line crosses the corners formed by the grid lines. Then count the number from top to bottom and divide that number by the number of blocks left to right (IF the scale is the same for both the x-axis and y-axis!) Then divide up-down number by left-right number. If it is the same, the slope is 1.

Here the line crosses the y axis at -1 exactly: (0, -1) The next place where it crosses the corner exactly is at (1, 5). Counting blocks: 6 from top to bottom, only 1 left to right 6/1

Or do it with the numbers: Find the difference in y-values, them divide by the difference in x-values, Using Coordinates (0,-1) and (1,5) the difference in y-values is 5-(-1) = 5+1 = 6 The difference in x-values is 1 - 0 = 1 6÷1 = 6

In her science classroom Jane noticed that the lengths (in inches) and the weights (in ounces) of the class's pet snakes were directly related by the equation y = kx, where x is the length and y is the weight. Use the information in the table to find k, the constant of proportionality?A.25.0 B.27.5 C.30.0 D.32.5

Answers

Answer:

Step-by-step explanation:

multiply by 2 then add half of the original number

The constant of proportionality(k) is 5/2 and the corresponding weight is

30 ounces for 12 inches.

What are ratio and proportion?

A ratio is a comparison between two similar quantities in simplest form.

Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.

In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.

Given, The lengths (in inches) and the weights (in ounces) of the class's pet snakes were directly related by the equation y = kx.

Now, when x = 6, y = 15

15 = 6k.

k = 15/6.

k = 5/2.

Now, when length(x) is 12 then,

y = 12(5/2).

y = 30.

Answer:

Step-by-step explanation:

4x + 6 = 102

-6. -6

4x= 96

x=24

Sum of all angles of triangle=180°

So, 102 + 4x + 6 + x = 180

or 5x + 108 = 180

or 5x = 180 - 108

or 5x = 72

or x = 72/5

or x = 14.5

So, x = 14.5°
