his week, Michael collected $468 for delivering newspapers. He had 40 repeat customers and 18 new ones. As an incentive, he charged the new subscribers $3 less than the repeat customers. If x represents the amount Michael collects from each repeat customer, which equation models this problem? What is the fee Michael charges each new subscriber?

Answers

Answer:

$6

Step-by-step explanation:

Let x be the amount Michael collects from each repeat customer

Since we are given that he charged the new subscribers $3 less than the repeat customers.

So, amount collects from each new customer = x-3

Since he had 40 repeated customers

So, the amount Michael collects from 40 repeat customer = $40x

Since he has 18 new customers

So, amount Michael collects from 18 new customer =$18(x-3)

We are also given that his week, Michael collected $468 for delivering newspapers.

Answer:

$6

40x+ 18 (x-3) = 468

Miranda and Savannah are excited that a new store just opened in town! They go together the first day it opens! Each time Miranda goes to the store she plans to spend $7dollar sign, and each time Savannah goes to the store she plans to spend $9A a few weeks from now, Miranda and Savannah are surprised to find out that they have spent the exact same total amount of money at the store.

Answers

Given :

Miranda goes to the store she plans to spend $7dollar sign, and each time Savannah goes to the store she plans to spend $9 sign a few weeks from now.

Miranda and Savannah are surprised to find out that they have spent the exact same total amount of money at the store.

To Find :

Least possible number of times that Miranda has been to the store.

Solution :

It is common to see that :

7 dollar/visit ×9 visits = $63

9 dollar/visit ×7 visits = $63

Therefore, minimum number of times Miranda has been to the store is 9.

Hence, this is the required solution.

Answer: 9 times

how to determine proportional relationship?

In your own words PLEASE

Answers

Answer:

to examine the ratio y/x (instead of x/y). If the x and y coordinates form proportional relationships, then there is some non-changing number (a constant) that when multiplied times x will create y. In this example, that number is 3 (y = 3x), and is called the constant of proportionality.

Step-by-step explanation:

In a graph the line must pass through the origin and it has to be a straight line,

In an table the y over x has to be the same for each one

a teacher has created a 100 point test with 22 questions. If each multiple choice question is worth 4 points and each short answer is worth 6 points. How many of each type are on the test?

Answers

Answer:

There are 16 multiple choices and 6 short answers.

Step-by-step explanation:

Let the number of multiple choice questions be x and the number of short answer questions be y.

x + y = 22 (total number of questions)

4x + 6y = 100 (total number of points)

x = 22 - y

4(22 - y) + 6y = 100

88 - 4y + 6y = 100

2y = 100 - 88

y = 6

x + 6 = 22

x = 16

Hence, there are 16 multiple choices and 6 short answers.

Hope this helped!

One of the angle of the triangle is 90 degrees which means it is a right angled triangle. Two angles are same i.e 45 degrees which means the angle is an isosceles triangle.

so, x = 17 (isosceles triangle)

then use pythagoreas theorem:

[tex]y = \sqrt{x {}^{2} + 17 {}^{2} } [/tex]

and x = 17, so simplify and

[tex]y = \sqrt{17 {}^{2} + 17 {}^{2} } [/tex]

so

[tex]y = 17 \sqrt{2} [/tex]

what is the slope of у>- 2х + 3

Answers

Answer:

Step-by-step explanation:

Graph

y > −2x + 3

Use the slope-intercept form to find the slope and y-intercept.

The slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

y = mx + b

Find the values of m and b using the form y = mx + b. m = −2

b = 3

The slope of the line is the value of m, and the y-intercept is the value of b.

Slope: −2

intercept: (0, 3)

Graph a dashed line, then shade the area above the boundary line since y is greater than

In 2001, 32 out of 80 members of New Jersey's House of Representatives were Democrats and 25 out of 60 members of Oregon's House of Representatives were Democrats. For each state, write a fraction for the number of Democrats in the House to the total number of House members. Which state had a greater fraction of Democrats in its House of Representatives?

Answers

Answer: Oregon

Step-by-step explanation:

For New Jersey:

Number of house of Representatives members = 80

Number of Democrats = 32

Fraction = 32/80 = 2/5

For Oregon:

Number of house of Representatives members = 60

Number of Democrats = 25

Fraction = 25/60 = 5/12

The state that has a greater fraction of Democrats in its House of Representatives is Oregon. This is because 5/12 is greater than 2/5.

Write a linear function g with g(0) = 9 and g(8) = 7.

Answers

Answer:

4y = 36-x

Step-by-step explanation:

A linear function is in the form

y = mx + b

for g(0) = 7 ;

x = 0 and y = 9

So ;

9= 0(x) + b

b = 9

For g(8) = 7

x = 8 and y = 7

7 = 8m + 9

7-9 = 8m

8m = -2

m = -2/8 = -1/4

So the equation is;

y = -1/4x + 9

Find the rate of discount when M_P=Rs 2500 and S.P =Rs_2350 The price of a T. V set inclusive of sales tax is RS 33660_If the rate of sales tax is 10% find its basic price.

Answers

Answer:

Step-by-step explanation:

The question is in two parts

For the first part;

Mark up price = 2500

Selling price = Rs 2350

To get the discount rate we will use the expression

Discount = MP-SP/MP× 100

Discount = 2500-2350/2500 × 100

Discount =150/2500 × 100

Discount percent = 150/25

discount percent = 6%

For the second part;

Cost of TV = Rs 33660 (including tax)

Sales tax = 10%

Increment = 10% of 33660

Increment = 0.1×33660

Increment = Rs 3366

Basic price = sales price (including tax)-increment

Basic price = 33660-3366

Basic price = Rs 30,294
