Answer:

$4.75

Step-by-step explanation:

The constant in this proportionality is the number that will not change. The number that won't change is the price of the bracelet.

Simply find the price by dividing the price of 2 bracelets ($9.50) with the amount of bracelets to get the price of ONE bracelet (2):

9.50/2 = 4.75

You want it to be greater than and equal to 2. A closed circle means to include 2 so you want a closed circle and to the right is to bigger numbers so you want to the right. So the answer is b. Number line with closed circle on 2 and shading to the right.

Suppose you pay $24 for a pair of shoes that has been discounted 20%. What is the original price of the shoes? Show how you iden

Rudik [331]

HOW TO WORK OUT
cross multiply so $24 is 80% because it was 20% discounted so..
24 = 80%
? = 100%

24 x 100 = 2400
2400 divided by 80 = 30

$30 was the original price

HOW TO CHECK
20% of $30
again you cross multiply so..
$30 = 100%
? = 20%

30 x 20 = 600
600 divided by 100 = 6
$30 - $6 = $24 which was the discounted pricw

Two kinds of tickets to an outdoor concert were sold: lawn tickets and seat tickets. fewer than 400 tickets in total were sold.

Natali [406]

Answer:

Part a) $x+y < 400$

Part b) The graph in the attached figure

Part c) see the explanation

Part d) The number of seat tickets sold must be less than 300 tickets

Step-by-step explanation:

Part a) write an inequality to describe the constraints. specify what each variable represents

Let

x ----> number of lawn tickets sold

y ----> number of seat tickets sold

we know that

The sum of the number of lawn tickets sold plus the number of seat tickets sold must be less than 400 tickets

The linear inequality that represent this situation is

$x+y < 400$

Part b) use graphing technology to graph the inequality. sketch the region on the coordinate plane

we have

$x+y < 400$

using a graphing tool

The solution is the triangular shaded area of positive integers (whole numbers) of x and y

see the attached figure

Remember that the values of x and y cannot be a negative number

Part c) name one solution to the inequality and explain what it represents in that situation

we know that

If a ordered pair lie on the solution of the inequality, then the ordered pair is a solution of the inequality (the ordered pair must satisfy the inequality)

I take the point (200,100)

The point (200,100) lie on the triangular shaded area of the solution

<u><em>Verify</em></u>

Substitute the value of x and the value of y in the inequality and compare the result

For x=200,y=100

$x+y < 400$

$200+100 < 400$
