Shopping at clothing world, jenna buys her children four shirts and three pairs of pants for 124.25. She returns the next day an

Aleksandr-060686 [28]

The cost of one shirt is 12.50 and cost of one pair of jeans is 24.75

Step-by-step explanation:

Let,

Cost of one shirt = x

Cost of pair of jeans = y

According to given statement;

4x+3y=124.25 Eqn 1

3x+5y=161.25 Eqn 2

Multiplying Eqn 1 by 3

$3(4x+3y=124.25)\\12x+9y=372.75\ \ \ Eqn\ 3$

Multiplying Eqn 2 by 4

$4(3x+5y=161.25)\\12x+20y=645\ \ \ Eqn\ 4$

Subtracting Eqn 3 from Eqn 4

$(12x+20y)-(12x+9y)=645-372.75\\12x+20y-12x-9y=272.25\\11y=272.25$

Dividing both sides by 11

$\frac{11y}{11}=\frac{272.25}{11}\\y=24.75$

Putting 24.75 in Eqn 1

$4x+3(24.75)=124.25\\4x+74.25=124.25\\4x=124.25-74.25\\4x=50$

Dividing both sides by 4

$\frac{4x}{4}=\frac{50}{4}\\x=12.50$

The cost of one shirt is 12.50 and cost of one pair of jeans is 24.75

P is the set of natural numbers that are less than 12

Damm [24]

Answer:

{ 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 }

Step-by-step explanation:

As per the definition, a natural number is a counting number (non-fractional number) that is greater than zero, but not equal to zero.

A set of natural numbers below 12 (but not including 12, because such isn't specified) would henceforth be;

{ 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 }

How would I solve this?

Norma-Jean [14]

Answer:

AB = 1.33

Step-by-step explanation:

AB and QR are in a ratio of 3 to 8 so we can create this proportion:

(3x+5)/24 = 3/8

cross-multiply:

8(3x+5) = 72

divide each side by 8 to get:

3x + 5 = 9

3x = 4

x = 4/3 or 1.33 repeating

Which input value produces the same output value for the

Tju [1.3M]

Answer: $d)x=4$

Step-by-step explanation:

<h3> The missing graph is attached.</h3><h3> And the options are:</h3>

$a)x=-1\\b)x=0\\c)x=3\\d)x=4$

By definition, a relation is a function if and only if each input value has one and only one output value.

It is important to remember that the input values are the values of "x" and the output values are the values of "y".

Observe the graph attached.

You can identify in the graph that the function f(x) and the function g(x) intersect each other at the following point:

$(4,3)$

Where the x-coordinate (input value) is:

$x=4$

And the y-coordinate (output value) is:

$y=3$

Therefore, you can conclude that the input value that produces the same output value for the two functions on the graph, is:

$x=4$
