A vendor sold a total of 413 large fries and souvenir sodas in one day. The total sales were $1068. Large fries cost $1.20 and souvenir sodas cost $3. Which system of linear equations can be used to find L, the number of large fries sold, and S, the number of souvenir sodas sold?

Answers

Answer:

[tex]L+S=413----------------1\\\\1.2L+3S=1068---------2[/tex]

Step-by-step explanation:

Step one:

given data

A vendor sold a total of 413 fries

Large fries cost $1.20 and souvenir sodas cost $3

let  L be the number of large fries sold and S be the number of  souvenir sodas

so

L+S=413

and

1.2L+3S=1068

Therefore the system of equation is

[tex]L+S=413----------------1\\\\1.2L+3S=1068---------2[/tex]

6x – 6= 3x and x – 1= 3x are not equivalent because why ?

Answers

6x - 6 = 3x

x = 2


x - 1 = 3x
-1 = 2x
x = -.5

They aren’t equivalent because the first x value is 2 and the second x value is -.5.

In a batch of 500 calculators, 25 were found to be defective. What is the probability that a calculator chosen at random will be defective? Write the probability as a percent.

Answers

Answer: 5%

Step-by-step explanation:

Probability for any event = [tex]\dfrac{\text{Number of favorable outcomes}}{\text{total outcomes}}[/tex]

Given: Number of defective calculators = 25

Total calculators = 500

The probability that a calculator chosen at random will be defective= [tex]\dfrac{25}{500}[/tex]

[tex]=0.05[/tex]

[tex]=0.05\times100\%\\\\= 5\%[/tex]

What is the image of (5,0) after a dilation by a scale factor of 3 centered at the origin?

Answers

Given:

The point (5,0) dilated by a scale factor of 3 centered at the origin.

To find:

The coordinates of image.

Solution:

If a figure dilated by a scale factor of k centered at the origin, then the rule of transformation is

[tex](x,y)\to (kx,ky)[/tex]

The point is dilated by a scale factor of 3 centered at the origin, then the rule of transformation is

[tex](x,y)\to (3x,3y)[/tex]

The given point is (5,0). Putting x=5 and y=0, we get

[tex](5,0)\to (3(5),3(0))[/tex]

[tex](5,0)\to (15,0)[/tex]

Therefore, the image of (5,0) is (15,0).
