the total cost of a bus ride and a ferry ride is $8.00. in one month, bus fare will increase by 10% and ferry fare will increase

ipn [44]

The bus fare is x, and the ferry fare is y.

x + y = 8

The bus fare will increase by 10% and the ferry fare will increase by 25%.

1.1x + 1.25y = 9.25

Multiply the first equation by -1.1:

-1.1x - 1.1y = -8.8

Add this to the original second equation.

0.15y = 0.45

y = 3

x + y = 8

x + 3 = 8

x = 5

The bus fare is $5, and ferry fare is $3.

Keisha bought cups of coffee and bagels for the people in her office. Each bagel cost $2 and each cup of coffee cost $1.50. Keis

-Dominant- [34]

Answer:

The number of bagels is <u>11</u> and the cups of coffee is <u>12</u>.

Step-by-step explanation:

Given:

Keisha bought cups of coffee and bagels for the people in her office. Each bagel cost $2 and each cup of coffee cost $1.50.

Keisha spent a total of $40 to buy 23 items.

Now, to find the number of cups of bagels and coffee.

As given in question:

Let $x$ represent the number of bagels.

And $y$ represent the number of cups of coffee.

So, the total number of items:

$x+y=23$

$x=23-y$ ......(1)

Now, the total money spent on items:

$2x+1.50y=40$

Substituting the value of $x$ from equation (1):

$2(23-y)+1.50y=40$

$46-2y+1.50y=40$

$46-0.50y=40$

<em>Subtracting both sides by 46 we get:</em>

$-0.50y=-6$

<em>Dividing both sides by -0.50 we get:</em>

$y=12.$

<em>The number of cups of coffee = 12.</em>

Now, to get the number of bagel we substitute the value of $y$ in equation (1):

$x=23-y$

$x=23-12$

$x=11.$

<em>The number of bagels = 11.</em>

Therefore, the number of bagels is 11 and the cups of coffee is 12.

<h3>Answer:</h3>

F (3x, 3y)

<h3>Explanation:</h3>

Dilation about the origin multiplies each coordinate by the dilation factor. For some coordinates (x, y), dilation by a factor of 3 means the new coordinates are ...

... 3×(x, y) = (3x, 3y)

_____

<em>Comment on the problem</em>

The way the problem is worded, you expect an answer choice that will be specific to the coordinates of point A. There are none.

Instead, the answer choices are generic, corresponding to dilation of a point (x, y) by a factor of 3, translation up and to the right by 3, dilation by a factor of 1/3, and translation down and to the left by 3.
